mmc: tegra: support Tegra124
Tegra124's MMC controller is very similar to earlier SoC generations,
and can be supported by the same driver.
However, there are some non-backwards-compatible HW differences, and
hence a new DT compatible value must be used to describe the HW. This
patch updates the driver to support that new compatible value.
That said, the HW differences are only relevant when enabling certain
high-performance transfer modes. Since the driver is currently very
simple and doesn't enable those modes, we don't actually need to address
any of these HW differences in the code yet, hence the simple nature of
this patch.

ARM: tegra: don't exceed AVP limits when configuring PLLP
Based on the Tegra TRM, the system clock (which is the AVP clock) can
run up to 275MHz. On power on, the default sytem clock source is set to
PLLP_OUT0. In function clock_early_init(), PLLP_OUT0 will be set to
408MHz which is beyond system clock's upper limit.
The fix is to set the system clock to CLK_M before initializing PLLP,
and then switch back to PLLP_OUT4, which has an appropriate divider
configured, after PLLP has been configured
Implement this logic in new function tegra30_set_up_pllp(),
which sets up PLLP and all PLLP_OUT* dividers, and handles the AVP
clock switching. Remove the duplicate PLLP setup from pllx_set_rate()
and adjust_pllp_out_freqs().

As a consequence on execution after relocation "initcall_run_list" will

it is dangerous because after relocation we don't expect initially used

For files where we actually have extent indexes following
an extent header (ext_block->eh_depth != 0), the do/while
loop from ext4fs_get_extent_block() does not select the
proper extent index structure.
the do/while loop will exit with i set to 0 and the
ext4fs_get_extent_block() function will return 0, even if
there was a valid extent index structure following the
header.

ext4fs: use EXT2_BLOCK_SIZE instead of fs->blksz
Using fs->blksz in ext4fs_get_extent_block() is not
correct since fs->blksz is not initialized on the
read path. Use EXT2_BLOCK_SIZE() instead which will
produce the desired output.

fs/ext4: fix calling put_ext4 with truncated offset
Curently, we are using 32 bit multiplication to calculate the offset,
so the result will always be 32 bit.
This can silently cause file system corruption when performing a write
operation on partition larger than 4 GiB.
This patch address the issue by simply promoting the terms to 64 bit,
and let compilers decide how to do the multiplication efficiently.

nand, gpmc: fix reading after switching ecc
The omap_gpmc allows switching ecc at runtime. Since
the NAND_SUBPAGE_READ flag is only set, it is kept when
switching to hw ecc, which is not correct. This leads to
calling chip->ecc.read_subpage which is not a valid
pointer. Therefore clear the flag when switching ecc so
reading in hw mode works again.

vexpress/armv8: Fix incorrect ethernet controller
This patch enables ethernet support in ARMv8 foundation model. The ARMv8
foundation model supports a SMSC91C111 integrated MAC and PHY module
which is present at base address 0x01A000000.
The previous implementation had enabled SMSC9115 ethernet controller
which is not present on the ARMv8 foundation model.
Tested on ARMv8 foundation model v1 and v2 by running ping/tftp
between the foundation model and the host PC via a bridged network.
Such improvement is possible due to reduction of the need to invalidate
redundant data, which resides in L2 cache.
Since the sent USB request size at once is 512B (L1 - 32 KiB in total) -
one can be quite confident that it is already available in L1 and L2 can
be disabled.

config: Update envs for trats and trats2 - new entries for new partitions
This patch adds extra dfu_alt_info entries to support storing the whole BOOT
, DATA and UMS partitions.
This allows upgrade of uImage and device tree blob (dtb) files at once.
Now it is also possible to store ext4 rootfs prepared with well established
linux tools (like mkfs.ext4).
