Before this commit, the mmc devices were always registered

In case of possibility to boot from more then one device,
the CONFIG_SYS_MMC_ENV_DEV should always point to right mmc device.
This can be achieved by init boot device as first, so it will be
always registered as mmc 0. Thanks to this, the 'saveenv' command
will work fine for all mmc boot devices.
Exynos based boards usually uses mmc host channels configuration:
- 0, or 0+1 for 8 bit - as a default boot device (usually eMMC)
- 2 for 4bit - as an optional boot device (usually SD card slot)
And usually the boot order is defined by OM pin configuration,
which can be changed in a few ways, eg.
- Odroid U3 - eMMC card insertion -> first boot from eMMC
- Odroid X2/XU3 - boot priority jumper
By this commit, Exynos dwmmc driver will check the OM pin configuration,

sunxi: Machine id hack to prevent loading buggy sunxi-3.4 kernels
Right now U-Boot supports the CONFIG_OLD_SUNXI_KERNEL_COMPAT option,
which makes it go out of its way in limiting the selection of PLL clock
frequencies and PMIC voltages in order not to upset outdated buggy
sunxi-3.4 kernel releases. And if the CONFIG_OLD_SUNXI_KERNEL_COMPAT
option is not set, then booting such old kernels exhibits various
failures at runtime. This is very user unfriendly, and there were
already several incidents when people wasted their time being hit
by these runtime failures and trying to debug them.
The right solution is not to add hacks and workarounds to the mainline
U-Boot, but to fix these bugs in the sunxi-3.4 kernel. And in fact,
the updated sunxi-3.4 kernels already exist. Still we need to follow
the 'Principle of Least Surprise' and U-Boot needs to ensure that
the old buggy kernels are not getting happily booted when the
CONFIG_OLD_SUNXI_KERNEL_COMPAT option is not set. And this patch
addresses this particular issue.
This patch makes U-Boot store the 'compatibility revision' number in
the top 4 bits of the machine id and pass it to the kernel. The old
buggy kernels will fail to load with a very much googlable error
message on the serial console (the "r1 = 0x100010bb" part of it):
"Error: unrecognized/unsupported machine ID (r1 = 0x100010bb)"
This error message can be documented in the linux-sunxi wiki with
proper explanations about how to resolve this situation and where
to get the necessary bugfixes for the sunxi-3.4 kernel.
The fixed sunxi-3.4 kernels implement a revision compatibility check
and clear the top 4 bits of the machine id if everything is alright.
By accepting the machine id with the bits 31:28 set to 1, the sunxi-3.4
kernel effectively certifies that it has the PLL5 clock speed and
AXP209 DCDC3 voltage fixes applied.
It is still possible to set the CONFIG_OLD_SUNXI_KERNEL_COMPAT option
in U-Boot if the user desires to use an outdated unpatched sunxi-3.4
kernel.

will honor this and add this device as a console (next to the primary

ARM: prepare for moving SoC sources into mach-*
In U-boot, the directory structure, arch/$(ARCH)/cpu/$(CPU)/$(SOC)/
has been adopted except that $(CPU) is missing from some
architectures and $(SOC) is missing from some CPUs.
This structure did not fit very well in some cases.
[1] AT91
AT91 SoC family have been developed across some ARM processor
generations. Generally speaking, some IPs are often re-used in the
same SoC family (same SoC vendor) even when the main processor is
updated. As a result, a SoC-common directory is needed in the upper
level. Currently, AT91 source files are placed as follows:
arch/arm/cpu/arm920t/at91/*
arch/arm/cpu/arm926ejs/at91/*
arch/arm/cpu/armv7/at91/*
arch/arm/cpu/at91-common/*
Once directories are split, the motivation for refactorings across
CPU directories is lost. Some files in arm920t/at91/ and
arm926ejs/at91/ are so similar that they could be merged.
[2] Tegra
Tegra is a little bit special case where different CPUs are used for
SPL and the main U-boot. To obey the arch/$(ARCH)/cpu/$(CPU)/$(SOC)
structure, the source files must be placed across the CPUs,
again SoC-common directory is necessary in the upper level.
Moreover, there are several families in Tegra: Tegra20, Tegra30,
Tegra114, Tegra124. Here again, the tegra-common directory is needed
to contain commonly-used files.
Tegra directories have been sprinkled in the directory structure.
arch/arm/cpu/arm720t/tegra20
arch/arm/cpu/arm720t/tegra30
arch/arm/cpu/arm720t/tegra114
arch/arm/cpu/arm720t/tegra124
arch/arm/cpu/arm720t/tegra-common
arch/arm/cpu/armv7/tegra20
arch/arm/cpu/armv7/tegra30
arch/arm/cpu/armv7/tegra114
arch/arm/cpu/armv7/tegra124
arch/arm/cpu/armv7/tegra-common
arch/arm/cpu/tegra20-common
arch/arm/cpu/tegra30-common
arch/arm/cpu/tegra114-common
arch/arm/cpu/tegra124-common
arch/arm/cpu/tegra-common
As you see, splitting SoC code by the CPU is not going well,
especially for ARM.
Why don't we collect SoC-specific files into a single place?
A good example we can follow is Linux's arch/arm/mach-* structure.
This item was discussed in the following thread:
http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/188548/
Looks like I got some positive responses and we are almost ready to
start this movement.
This commit prepares arch/arm/Makefile for describing machdirs in it.
After this commit, we can move SoC directory to arch/arm/mach-$(SOC)
in simple steps although some cases such as AT91 and Tegra need more
fixes.
What we generally have to do is:
[1] Move files arch/arm/cpu/$(CPU)/$(SOC)/* to arch/arm/mach-$(SOC)/*
[2] Add machine entry into arch/arm/Makefile
[3] Remove "obj-y += $(SOC)" from arch/arm/cpu/$(CPU)/Makefile
[4] Fix the Kconfig file path in arch/arm/Kconfig
[5] Modify MAINTAINERS if necessary

serial: Support an early UART for debugging
This came up in a discussion on the mailing list here:
https://patchwork.ozlabs.org/patch/384613/
My concerns at the time were:
- it doesn't need to be written in assembler
- it doesn't need to be ARM-specific
This patch provides a possible alternative. It works by allowing any serial
driver to export one init function and provide a putc() function. These
can be used to output debug data before the real serial driver is available.
This implementation does not depend on driver model, and it is possible for
it to operate without a stack on some architectures (e.g. PowerPC, ARM). It
provides the same features as the ARM-specific debug.S but with more UART
and architecture support.

cmd_i2c: Provide option for bulk 'i2c write' in one transaction
I2C chips do exist that require a write of some multi-byte data to occur in
a single bus transaction (aka atomic transfer), otherwise either the write
does not come into effect at all, or normal operation of internal circuitry
cannot be guaranteed. The current implementation of the 'i2c write' command
(transfer of multiple bytes from a memory buffer) in fact performs a separate
transaction for each byte to be written and thus cannot support such types of
I2C slave devices.
This patch provides an alternative by allowing 'i2c write' to execute the
write transfer of the given number of bytes in a single bus transaction if
the '-s' option is specified as a final command argument. Else the current
re-addressing method is used.
