ext4fs_allocate_blocks() always allocates at least one block for a file.
If the file size is zero, this causes total_remaining_blocks to
underflow, which then causes an apparent hang while 2^32 blocks are
allocated.
To solve this, check that total_remaining_blocks is non-zero as part of
the loop condition (i.e. before each loop) rather than at the end of
the loop.

Before this commit, fdt_initrd() just returned if initrd

But it is possible if the RAM is located at address 0.
This commit makes the return condition more reasonable:

Data written to DTB must be converted to big endian order.
It is usually done by using cpu_to_fdt32(), cpu_to_fdt64(), etc.
fdt_initrd() invoked write_cell(), which always swaps byte order.
It means the function only worked on little endian architectures.
(On big endian architectures, the byte order should be kept as it is)
This commit uses cpu_to_fdt32() and cpu_to_fdt64()
and deletes write_cell().

Generic board support is now enabled for Exynos 4, and if any
init function returns an error then the init process is stopped.
This makes a boot issue on the Trats and Trats2 devices. If the device
is supplied by USB cable or an external power supply then it can't boot
because function exynos_power_init returns an error. Now this function
returns 0 if battery is not connected.

Commit e9fd66defd (ARM: mx6: define CONFIG_ARM_ERRATA_742230) enables
errata 742230 for imx6, because it helps remove one reboot issue.
However, this errata does not really apply on imx6, because Cortex-A9
on imx6 is r2p10 while the errata only applies to revisions r1p0..r2p2.
At a later time, commit f71cbfe3ca (ARM: Add workaround for Cortex-A9
errata 794072) adds support of errata 794072, which applies to all
Cortex-A9 revisions. As the workaround for both errata are exactly
same, it makes a lot more sense to select 794072 instead of 742230 for
imx6. Since we already enable 794072 for imx6, it's time to drop
errata 742230 to avoid confusion.

We also check the "is it locked" bits of PHY_CON13 and loop until they
show the the value sampled actually represents a locked value. It
doesn't appear that the glitching and "is it locked" are related, but
it seems wise to wait until the PHY tells us the value is good before
we use it. In practice we will not loop more than a couple times (and

This patch intends to remove all code which enables hardware read
leveling. All characterization environments may not cope up with
h/w read leveling enabled, so we must disable this.
Also, disabling h/w read leveling improves the MIF LVcc value
(LVcc value is the value at which DDR will fail to work properly).
Improving LVcc means we have enough voltage margin for MIF.
When h/w leveling is enabled, we have almost zero volatge margin.

- User plugs in an SD card
- Execute: mmc dev 1

I know that "mmc rescan" will force the HW to be reprobed, but I feel it
makes more sense if "mmc dev" always reprobes the HW after selecting the
