8212519254 powerpc/mpc85xx: work around erratum A-006593
Erratum A-006593 is "Atomic store may report failure but still allow
the store data to be visible".

The workaround is: "Set CoreNet Platform Cache register CPCHDBCR0 bit
21 to 1'b1.  This may have a small impact on synthetic write bandwidth
benchmarks but should have a negligible impact on real code."

Calculate reserved fields according to IFC bank count

1. Move csor_ext register behind csor register and fix res offset
2. Move ifc bank count to config_mpc85xx.h to support 8 bank count
3. Guard fsl_ifc.h with CONFIG_FSL_IFC macro to eliminate the compile

69fdf90010 powerpc/t4qds: Slave module for boot from SRIO and PCIE
When a T4 board boots from SRIO or PCIE, it needs to finish these processes:
	1. Set all the cores in holdoff status.
	2. Set the boot location to one PCIE or SRIO interface by RCW.
	3. Set a specific TLB entry for the boot process.
	4. Set a LAW entry with the TargetID of one PCIE or SRIO for the boot.
	5. Set a specific TLB entry in order to fetch ucode and ENV from
	   master.
	6. Set a LAW entry with the TargetID one of the PCIE ports for
	   ucode and ENV.
	7. Slave's u-boot image should be generated specifically by
	   make xxxx_SRIO_PCIE_BOOT_config.
	   This will set SYS_TEXT_BASE=0xFFF80000 and other configurations.

c8b281524b powerpc/boot: Change the macro of Boot from SRIO and PCIE master module
Currently, the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" can enable
the master module of Boot from SRIO and PCIE on a platform. But this
is not a silicon feature, it's just a specific booting mode based on
the SRIO and PCIE interfaces. So it's inappropriate to put the macro
into the file arch/powerpc/include/asm/config_mpc85xx.h.

Change the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" to
"CONFIG_SRIO_PCIE_BOOT_MASTER", remove them from
arch/powerpc/include/asm/config_mpc85xx.h file, and add those macros
in configuration header file of each board which can support the
master module of Boot from SRIO and PCIE.

In current code FIFO_DEPTH is getting calculated after reading the default FIFOTH

Instead of storing the correct value, we were recalculating the FIFO_DEPT each
time which is not correct.

Use a negative value of CONFIG_ENV_OFFSET for all NVIDIA reference boards
that store the U-Boot environment in the 2nd eMMC boot partition. This
makes U-Boot agnostic to the size of the eMMC boot partition, which can

5c088ee841 env_mmc: allow negative CONFIG_ENV_OFFSET
A negative value of CONFIG_ENV_OFFSET is treated as a backwards offset
from the end of the eMMC device/partition, rather than a forwards offset
from the start.

This is useful when a single board may be stuffed with different eMMC
devices, each of which has a different capacity, and you always want the
environment to be stored at the very end of the device (or eMMC boot
partition for example).

One example of this case is NVIDIA's Ventana reference board.

f866a46d6e mmc: report capacity for the selected partition
Enhance the MMC core to calculate the size of each MMC partition, and
update mmc->capacity whenever a partition is selected. This causes:

mmc dev 0 1 ; mmcinfo

... to report the size of the currently selected partition, rather than
always reporting the size of the user partition.

01b77353e4 fsl_esdhc: Do not clear interrupt status bits until data processed
After waiting for the command completion event, the interrupt status
bits, that occured to be set by that time, are cleared by writing them
back. It is supposed, that it should be command related bits (command
complete and may be command errors).

However, in some cases the DMA already completes by that time before
the full transaction completes. The corresponding DINT bit gets set
and then cleared before even entering the loop, waiting for data part
completion. That waiting loop never gets this bit set, causing the
operation to hang. This is reported to happen, for example, for write
operation of 1 sector to upper area (block #7400000) of SanDisk Ultra II
8GB card.

The solution could be to explicitly clear only command related interrupt
status bits. However, since subsequent processing does not rely on
any command bits state, it could be easier just to remove clearing
of any bits at that point, leaving them all until all data processing
completes. After that the whole register will be cleared at once.

Also, on occasion, interrupts masking moved to before writing the command,
just for the case there should be no chance of interrupt between the first
command and interrupts masking.

c2137b10a4 mmc: fsl_esdhc: Fix hang after 'save' command
Since commit 48e0b2bd (powerpc/esdhc: Correct judgement for DATA PIO mode)
we see mx6 systems to hang after doing a 'save' command.

Revert this commit since the original 'ifdef' logic from 7b43db92
(drivers/mmc/fsl_esdhc.c: fix compiler warnings) was the correct one.

a586c0aa21 mmc write bug fix
This patch fixes a bug related to mmc writes.

When doing fatwrites on an SD-Card, MMC bus problems can occur. Depending
on the size of the file, "MMC0: Bus busy timeout!" is reported, resulting
in an SD-Card that is no longer responding.
It appears to be, that set_cluster can be called with a size being zero.
That can be with a file that has a size being an exact multiple
(including 0) of the clustersize, but also for files that are smaller than
the size of one cluster.
The same problem occurs if the "mmc write" command is given with a block
count being 0.

By adding a check for the block count being zero in mmc_write_blocks
(drivers/mmc.c), this problem is solved.

1695b29a5d mmc: sdhci: Enable 8-bit bus width only for 3.0 spec onwards
CAP register don't have any information for 8-bit buswidth support
on 2.0 sdhci spec, only from 3.0 onwards bit[18] got this information.

Due to this misassignment in sdhci, mmc is setting 8-bit buswidth using
mmc_set_bus_width even if controller doesn't support.
Below change has code information.
"mmc: Properly determine maximum supported bus width"
(sha1: 7798f6dbd5)

Bug log: <mmc plus and emmc cards)
-------
zynq-uboot> mmcinfo
Error detected in status(0x208100)!
Device: zynq_sdhci
Manufacturer ID: fe
.....

So enable 8-bit support only for 3.0 spec using CAP and for below 3.0
assign mmc->host_caps = MMC_MODE_8BIT on respective platform driver
if host have a support.
