Commit ddc94378d changed the definition of __kernel_size_t
from unsigned int to unsigned long.
It is true that it fixed warnings on some crosstools
but it increased warnings on the others.
The problem is that we cannot see consistency in terms of
the typedef of __kernel_size_t on M68K architecture.
However, I'd like to suggest to have __kernel_size_t to be
unsigned int again.
Rationale:
[1] Linux Kernel defines __kernel_size_t on M68K as unsigned int.
Let's stick to the Linux's way.
[2] We want to build boards with popular pre-built toolchains,
not the one locally-built by indivisuals.
I think m68-linux-gcc which can be downloaded from www.kernel.org
is the candidate for our _recommended_ toolchains.
With this patch, all the m68k boards can be built without any warnings.
Give it a try with the following crosstools:
https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.6.3/
x86_64-gcc-4.6.3-nolibc_m68k-linux.tar.xz
or
https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/
x86_64-gcc-4.9.0-nolibc_m68k-linux.tar.xz
(The latter is newer.)

The pad settings for DISP0_DATA02 and DISP0_DAT10 were not
set in the same way as DISP0_DAT00-23, causing much flicker
in parallel RGB displays on Dual-Lite and Solo processors.
These settings now match the i.MX6 Dual and Quad core versions.

The csarX and cscrX registers in the fbcs_t struct are 16-bit for

The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF
images and u-boot, and does this for virtual platforms by using
semihosting. This commit extends this idea by allowing u-boot to also
use semihosting to load the kernel/ramdisk/dtb. This eliminates the need
for a bootwrapper and produces a more realistic boot sequence with
virtual models.
Though the semihosting code is quite generic, support for armv7 in
fastmodel is less useful due to the wide range of available silicon
and the lack of a free armv7 fastmodel, so this change contains an
untested armv7 placeholder for the service trap opcode.
Please refer to doc/README.semihosting for a more detailed description
of semihosting and how it is used with the armv8 virtual platforms.

I2C read transactions are typically implemented as follows:
START(write) address REPEATED_START(read) data... STOP
However, Tegra's I2C driver currently implements reads as follows:
START(write) address STOP START(read) data... STOP
This sequence confuses at least the AS3722 PMIC on the Jetson TK1 board,
leading to corrupted read data in some cases. Fix the driver to chain
the transactions together using repeated starts to solve this.
