77f6dabc0a board: gateworks: venice: add fixup for GW73xx-C+
The GW73xx-C revision and onward replaced the 5-port PCIe switch with a
4-port (dropping PCIe to one of the miniPCIe sockets) due to part
availability. This moved the PCI bus of the GbE eth1 device. Use a fixup
to adjust the dt accordingly so that local-mac-address assigned from dt
works on new revision boards.

While we are at it, rename 'blob' to 'fdt' for clarity.

a18f23f977 arm: dts: imx8mn-beacon-kit-u-boot: Fix broken booting
When the imx8mm.dtsi file was pulled in from Linux, the UARTs
were moved into an spba sub-node which wasn't being included
in the SPL device tree.  This meant the references to the UART
weren't being handled properly and when booting the system would
constantly reboot.  Fix this by adding the spba node to the spl
device tree to restore normal booting.

mmc: fsl_esdhc_spl: Add support for builds without CONFIG_SYS_MMC_U_BOOT_OFFS
When fixed offset via CONFIG_SYS_MMC_U_BOOT_OFFS is not specified then
expects that U-Boot proper is placed immediately after SPL without any
additional padding.

This allows to generate smaller SPL+U-Boot final binary as it is not
required to specify fixed offset to U-Boot proper at SPL compile time.

In this case offset to U-Boot proper is calculated at SPL compile time in
linker script.

Makefile: Reduce usage of custom mpc85xx u-boot.bin target
Building of final u-boot.bin binary for mpc85xx via binman is needed only
when inserting DTB binary in the middle of the u-boot ELF binary (before
.bootpg and .resetvec ELF sections).

These requirements are met when CONFIG_MPC85XX_HAVE_RESET_VECTOR is enabled
(= generating .bootpg/.resetvec sections) and CONFIG_OF_SEPARATE is enabled
(= inserting DTB binary).

So in all other cases use standard build procedure instead of custom
mpc85xx u-boot.bin Makefile target via binman.

Makefile: Build final mpc85xx non-SPL image in standard file u-boot.bin
Currently Makefile produces final mpc85xx image when SPL is not used in
custom file u-boot-with-dtb.bin. It is quite confusing name as build
process produce also intermediate file standard file u-boot-dtb.bin (which
is just intermediate and not bootable). Other platforms use u-boot.bin
(UBOOT_BIN) as standard name for final bootable raw image.

So change Makefile rules and binman to produce final bootable file for
mpc85xx also into file u-boot.bin. There is just need for mpc85xx to not
define default rule for u-boot.bin then instruct binman (via DTS file) to
store final image into u-boot.bin (instead of u-boot-with-dtb.bin) and
finally rename target u-boot-with-dtb.bin to u-boot.bin.

With this change are also removed custom Makefile hacks for mpc85xx that it
produced non-standard output file. And also updated documentation.

5818198e6a arm: mvebu: Fix moving internal registers
Commit 5bb2c550b1 ("arm: mvebu: Move internal registers in
arch_very_early_init() function") moved code from file cpu.c to lowlevel.c,
which moves Marvell internal registers from address INTREG_BASE_ADDR_REG to
SOC_REGS_PHY_BASE.

But the steps describing how to do it correctly were documented only in
older U-Boot versions and commit cefd764222 ("arm: mvebu: Fix internal
register config on A38x") probably unintentionally removed important
details about MMU from code comments around.

Commit 5bb2c550b1 ("arm: mvebu: Move internal registers in
arch_very_early_init() function") implemented code movement according to
(now incomplete) comments which resulted in semi-broken code.

The result is that I-cache is currently disabled for all Armada 38x boards
and maybe there are some other (unreported / undetected) issues.

Reimplement it correctly. First flush all caches, then disable MMU and L2
cache and then move Marvell internal registers. There is no need to
explicitly disable I-cache.

After this change lzmadec command with lzma image of 0x7000000 bytes is
doing decompression just 5 seconds. Before this change it was 30 seconds.

To make lowlevel.S code more readable, extend asm/pl310.h header file to be
compatible with assembler and use macros from this file.

4f2333ba88 arm: mvebu: Enable L2 cache also on Armada 38x
For some unknown reason when L2 cache is disabled on Armada 385 then loadb,
loadx and loady commands do not work with higher baudrates than 115200
(they just abort transfer) and lzmadec command with lzma image of size
0x7000000 (maybe even smaller, we tested this one) is doing decompression
for more than 2 minutes. After enabling L2 cache decompression takes only
30s and loadb, loadx and loady are stable and working fine.

git bisect identified problematic commit 3308933d2f ("arm: mvebu: Avoid
reading MVEBU_REG_PCIE_DEVID register too many times"). Before this commit
above issues were not present.

But investigation showed that above issue was possible to reproduce also by
reverting that commit and forcing compiler to do inline optimization of
mvebu_soc_family() function. Which seems that the root of this issue is in
caches and position of instruction of segments. So currently it is unknown
what is or was broken, but code movement, code inlining or other compiler
optimization triggered it.

Commit 3e5ce7ceeb ("arm: mvebu: Enable L2 cache on Armada XP") mentioned
that enabling L2 cache on Armada XP improved performance and that Armada
38x has L2 disabled (which is default state) and if needed it has to be
enabled in separate patch. As enabling L2 cache also improve performance
on Armada 38x, enable it.

Note that Aurora cache in no outer mode is available only on Armada XP,
hence it is not touched for Armada 38x code.

condition. Fix this issue by checking for AXP platform, not by A38X.

117ef65502 arm: mvebu: Fix function enable_caches
Commit 3308933d2f ("arm: mvebu: Avoid reading MVEBU_REG_PCIE_DEVID
register too many times") broke support for caches on all Armada SoCs.

Before that commit there was code:

    if (mvebu_soc_family() != MVEBU_SOC_A375) {
        dcache_enable();
    }

And after that commit there is code:

    if (IS_ENABLED(CONFIG_ARMADA_375)) {
        dcache_enable();
    }

Comment above this code says that d-cache should be disabled on Armada 375.
But new code inverted logic and broke Armada 375 and slowed down all other
Armada SoCs (including A38x).

Fix this issue by changing logic to:

    if (!IS_ENABLED(CONFIG_ARMADA_375)) {
        dcache_enable();
    }

Which matches behavior prior that commit.

cadda05a76 arm: mvebu: turris_omnia: Allow to use second serial port
Turris Omnia has two serial ports. Both are already specified in device
tree file. But U-Boot by default does not allow to use more than one serial
port unless CONFIG_SERIAL_PROBE_ALL is not enabled.

After enabling CONFIG_SERIAL_PROBE_ALL, U-Boot see also second serial port
(but is inactive by default):

    => coninfo
    List of available devices:
    serial@12000 00000007 IO stdin stdout stderr
    serial@12100 00000007 IO

To allow simultaneously to use more input / output devices it is needed to
enable CONFIG_CONSOLE_MUX option.

With CONFIG_CONSOLE_MUX it is possible to call:

    => setenv stdout 'serial@12000,serial@12100'

And U-Boot output is then visible on both serial ports.

634aa8e586 tools: termios_linux.h: Fix compilation on non-glibc systems
TCGETS2 is defined in header file asm/ioctls.h provided by linux kernel.
On glib systems it is automatically included by some other glibc include
header file and therefore TCGETS2 is present in termios_linux.h when
linux kernel provides it.

On non-glibc systems (e.g. musl) asm/ioctls.h is not automatically included
which results in the strange error that BOTHER is supported, TCGETS2 not
defined and struct termios does not provide c_ispeed member.

    tools/kwboot.c: In function 'kwboot_tty_change_baudrate':
    tools/kwboot.c:662:6: error: 'struct termios' has no member named 'c_ospeed'
      662 |   tio.c_ospeed = tio.c_ispeed = baudrate;
          |      ^

Fix this issue by explicitly including asm/ioctls.h file which provides
TCGETS2 macro (if supported on selected architecture) to not depending on
glibc auto-include behavior and because termios_linux.h requires it.

With this change it is possible compile kwboot with musl libc.

64c422b14f arm: mvebu: turris_mox: Add support for distroboot $fdt_addr
$fdt_addr is mandatory for systems which provides DTB in HW (e.g. ROM) and
wishes to pass that DTB to Linux.

Turris Mox contains DTB binary in SPI NOR memory at "dtb" partition which
starts at offset 0x7f0000 and is 0x10000 bytes long.

Armada 3700 CPU does not allow mapping SPI NOR memory into physical address
space like on other architectures and therefore set $fdt_addr variable to
memory range in RAM and loads this DTB binary from SPI NOR in misc_init_r()
function.

7bb9ea47e1 board: turris: Initialize serial# env
Store serial number from atsha cryptochip into the serial# env variable.
U-Boot automatically puts content of this variable into the root device
tree property serial-number when booting Linux kernel. Refactor turris
atsha code and from turris_atsha_otp_get_serial_number() function returns
directly string suitable for printing or storing into device tree. Because
during different boot stages is env storage read-only, it is not possible
to always store serial number into env storage. So introduce a new function
turris_atsha_otp_init_serial_number() which is called at later stage and
which ensures that serial number is correctly stored into env.

f7b0bbca2b cmd: mvebu/bubt: Check for A38x/A37xx OTP secure bits and secure boot
For obvious reasons BootROMS rejects unsigned images when secure boot is
enabled in OTP secure bits. So check for OPT secure bits and do not allow
flashing unsigned images when secure boot is enabled. Access to OTP via
U-Boot fuse API is currently implemented only for A38x and A37xx SoCs.

Additionally Armada 3700 BootROM rejects signed trusted image when secure
boot is not enabled in OTP. So add also check for this case. On the other
hand Armada 38x BootROM acceps images with secure boot header when secure
boot is not enabled in OTP.

OTP secure bits may have burned also boot device source. Check it also and
reject flashing images to target storage which does not match OTP.
