e895a4b06f fdt: Allow ft_board_setup() to report failure
This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.

Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.

Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

b940ca64b2 armv8/fsl-lsch3: Add support to load and start MC Firmware
Adding support to load and start the Layerscape Management Complex (MC)
firmware. First, the MC GCR register is set to 0 to reset all cores. MC
firmware and DPL images are copied from their location in NOR flash to
DDR. MC registers are updated with the location of these images.
Deasserting the reset bit of MC GCR register releases core 0 to run.
Core 1 will be released by MC firmware. Stop bits are not touched for
this step. U-boot waits for MC until it boots up. In case of a failure,
device tree is updated accordingly. The MC firmware image uses FIT format.

c48e686889 fdt_support: Add helper function to read "ranges" property
This patch adds a helper function that can be used to interpret most
"ranges" properties in the device tree.

It reads the n'th range out of a "ranges" array and returns the node's
virtual address of the range, the physical address that range starts at
and the size of the range.

2a523f5240 fdt: Add new fdt_set_node_status & fdt_set_status_by_alias helpers
Add common function fdt_set_node_status() to assist in various locations
that we set a nodes status.  This function utilizes the status values
that are part of the EPAPR spec (on power.org).

fdt_set_status_by_alias() is based on fdt_set_node_status() but uses an
alias string to identify the node to update.

We also add some shortcut functions to help the common cases of setting
"okay" and "disabled":

	fdt_status_okay()
	fdt_status_disabled()
	fdt_status_okay_by_alias()
	fdt_status_disabled_by_alias()

Finally, we fixup the corenet_ds ethernet code which previously had
a function by the same name that can be replaced with the new helpers.

8a805df136 ppc4xx/fdt/flash: Change fdt_fixup_nor_flash_node() to not rely on cs size
This patch changes the behaviour of the fdt_fixup_nor_flash_node()
function. Now it doesn't patch the size of the "reg" property with the
chip-select size, but with the size returned from the new function
flash_get_bank_size(). This function will return per weak default the
flash size of the bank (bank = chip-select numer) detected by the flash
driver. If this does not fit your needs, this function may be overridden
by a board specific one.

For this the parameters needed to be changed. So I intentionally squashed
the PPC4xx stuff using this routine into this patch. Otherwise it would
not be git-bisectable anymore.

The board specific function for the AMCC/APM Ebony eval board is now
included in this patch version.

8ab451c46b fdt: Added helper to set PCI dma-ranges property
Added fdt_pci_dma_ranges() that parses the pci_region info from the
struct pci_controller and populates the dma-ranges based on it.

The max # of windws/dma-ranges we support is 3 since on embedded
PowerPC based systems this is the max number of windows.

56844a22b7 powerpc: Fix bootm to boot up again with a Ramdisk
Commit 2a1a2cb6 didnt remove the dummy mem reservation in fdt_chosen,
and this stopped Linux from booting with a Ramdisk. This patch fixes
this, by deleting the useless dummy mem reservation.

When booting with a Ramdisk, a fix offset FDT_RAMDISK_OVERHEAD is now
added to of_size, so we dont need anymore a dummy mem reservation.

I measured the value of FDT_RAMDISK_OVERHEAD on a MPC8270 based
system (=0x44 bytes) and rounded it up to 0x80).

2a1a2cb6e2 fdt: refactor initrd related code
Created a new fdt_initrd() to deal with setting the initrd properties
in the device tree and fixing up the mem reserve.  We can use this
both in the choosen node handling and lets us remove some duplicated
code when we fixup the initrd info in bootm on PPC.

54f9c86691 bootm: Set working fdt address as part of the bootm flow
Set the fdt working address so "fdt FOO" commands can be used as part
of the bootm flow.  Also set an the environment variable "fdtaddr"
with the value.

ba37aa0328 fdt: rework fdt_fixup_ethernet() to use env instead of bd_t
Move to using the environment variables 'ethaddr', 'eth1addr', etc..
instead of bd->bi_enetaddr, bi_enet1addr, etc.

This makes the code a bit more flexible to the number of ethernet
interfaces.

Delete the crypto node if not on an E-processor.  If on 8360 or 834x family,
check rev and up-rev crypto node (to SEC rev. 2.4 property values)
if on an 'EA' processor, e.g. MPC8349EA.

18e69a35ef 83xx/fdt_support: let user specifiy FSL USB Dual-Role controller role
Linux understands "host" (default), "peripheral" and "otg" (broken).
Though, U-Boot doesn't restrict dr_mode variable to these values (think
of renames in future).

43ddd9c820 Remove deprecated CONFIG_OF_HAS_UBOOT_ENV and CONFIG_OF_HAS_BD_T
These defines embedded the u-boot env variables and/or the bd_t structure
in the fdt blob.  The conclusion of discussion on the u-boot email list
was that embedding these in the fdt blob is not useful: there are better
ways of passing the data (in fact, the fdt blob itself replaces the
bd_t struct).

The only board that enables these is the stxxtc and they don't appear
to be used by linux.

b8ec238503 85xx: add ability to upload QE firmware
Define the layout of a binary blob that contains a QE firmware and instructions
on how to upload it.  Add function qe_upload_firmware() to parse the blob and
perform the actual upload.  Add command-line command "qe fw" to take a firmware
blob in memory and upload it.  Update ft_cpu_setup() on 85xx to create the
'firmware' device tree node if U-Boot has uploaded a firmware.  Fully define
'struct rsp' in immap_qe.h to include the actual RISC Special Registers.
