Since commit 1517126fda ("ARM: uniphier: select DM_ETH"), DM-based
drivers/net/smc911x.c is compiled, but it is never probed because the
parent node lacks the DM-based driver.
I need a skeleton driver to populate child devices (but the next commit
will move more hardware settings to the this driver).
I put this to drivers/bus/uniphier-system-bus.c because this is the
same path as the driver in Linux kernel.

Currently, the supports for the following two ARMv7 SoC groups
are exclusive, because the boot ROM loads the SPL to a different
address:
- LD4, sLD8 (SPL is loaded at 0x00040000)
- Pro4, Pro5, PXs2, LD6b (SPL is loaded at 0x00100000)
This limitation exists only when CONFIG_SPL=y.
Instead of using crappy CONFIG options, checking SPL and SPL_TEXT_BASE
is cleaner.

I increased the maximum U-Boot proper size from time to time, but
configs/uniphier_v7_defconfig hit the current limit 832KB.
Some historical info:
In the initial support, the max size was 512MB.
Commit 58d702274c ("ARM: uniphier: increase CONFIG_SYS_MONITOR_LEN")
increased it to 576KB, and commit 3ce5b1a8d8 ("ARM: uniphier: move
SPL stack address") moved the SPL stack location to avoid the memory
map conflict. It was the solution to increase the size without changing
the NOR boot image map.
commit 1a4bd3a095 ("ARM: uniphier: increase CONFIG_SYS_MONITOR_LEN
again") ended up with increasing the max size again, breaking the NOR
boot image map. The limit was set to 832KB, otherwise the SPL stack
would overwrite the U-Boot proper image:
CONFIG_SPL_STACK - CONFIG_SYS_UBOOT_BASE + sizeof(struct image_header) = 0xd0000
To increase CONFIG_SYS_MONITOR_LEN even more, the SPL stack must be
moved somewhere. I put it back to the original location prior to
commit 3ce5b1a8d8.
With this change, there is no more practical size limit.

This reverts commit 45f41c134b.
This weird workaround was the best I came up with at that time
to boot U-Boot from TF-A.
I noticed U-Boot successfully boots on LD20 (i.e. CA72 CPU) by using
the latest TF-A.
Specifically, since the following TF-A commit, U-Boot runs at EL2
instead of EL1, and this issue went away as a side-effect.

However, if I reverted that, this problem would come back, presumably
because some EL1 code in U-Boot triggers this issue.
Now that commit f8ddd8cbb5 ("arm64: issue ISB after updating system

longer needed irrespective of the exception level at which U-Boot runs.

There might be hardware configurations where 64-bit data accesses
to XHCI registers are not supported properly. This patch removes
the readq/writeq so always two 32-bit accesses are used to read/write
64-bit XHCI registers, similarly as it is done in Linux kernel.
This patch fixes operation of the XHCI controller on RPI4 Broadcom
BCM2711 SoC based board, where the VL805 USB XHCI controller is
connected to the PCIe Root Complex, which is attached to the system
through the SCB bridge.
Even though the architecture is 64-bit the PCIe BAR is 32-bit and likely
the 64-bit wide register accesses initiated by the CPU are not properly
translated to a sequence of 32-bit PCIe accesses.
xhci_readq(), for example, always returns same value in upper and lower
32-bits, e.g. 0xabcd1234abcd1234 instead of 0x00000000abcd1234.

Since the mdio code got upstreamed it is not possible
to activate network ports on CP110 Master and Slave.
The problem is in mvpp2_base_probe which is called for each
CP110 and it initializes the buffer area for descs and rx_buffers.
This should only happen once though and the bd space is actually
set to 0 after the first run of the function.
This leads to an error when the second CP110 tries the initialization
again and disables all network ports on this CP110.
This patch adds a static variable to check if the buffer area is
initialized only once globally.

This adds a bunch of preprocessor magic to extend the capabilities of
CONFIG_IS_ENABLED. The existing semantics of
CONFIG_IS_ENABLED(FOO)
expanding to a 1 or 0 (depending on build context and the defined-ness
or not of the appropriate CONFIG_FOO/CONFIG_SPL_FOO/CONFIG_TPL_FOO)
are of course preserved. With this, one is also allowed a two-argument
form
CONFIG_IS_ENABLED(FOO, (something))
which expands to something precisely when CONFIG_IS_ENABLED(FOO) would
expand to 1, and expands to nothing otherwise. It is, in other words,
completely equivalent to the three lines
#if CONFIG_IS_ENABLED(FOO)
something
#endif
The second argument must be parenthesized in order to allow any
tokens, including a trailing comma, to appear - one use case for this
is precisely to make it a bit more ergonomic to build an array and
only include certain items depending on .config. That should increase
both readability and not least "git grep"ability.
A third variant is also introduced,
CONFIG_IS_ENABLED(FOO, (xxx), (yyy))
