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

So that the CONFIG_SPL_FEL option is not needed anymore. And the regular

A bunch of system registers need to be saved/restored in order to ensure

This patch adds basic constructs in the ARMv8 u-boot code
to handle and apply Cortex-A57 specific erratas.
As and example, the framework showcases how erratas 833069, 826974
and 828024 can be handled and applied.
Later on this framework can be extended to include other
erratas.

The Juno Development Platform is a physical Versatile Express
device with some differences from the emulated semihosting
models. The main difference is that the system is split in
a SoC and an FPGA where the SoC hosts the serial ports at
totally different adresses.

The Versatile Express ARMv8 semihosted FVP platform is still
using the legacy CONFIG_SYS_EXTRA_OPTIONS method to configure
some compile-time flags. Get rid of this and create a Kconfig
entry for the FVP model, and a selectable bool for the
semihosting library.
The FVP subboard is now modeled as a target choice so we can
eventually choose between different ARMv8 versatile express
boards (FVP, base model, Juno...) this way. All dependent
symbols are updated to reflect this.
The 64bit Versatile Express board symbols are renamed
VEXPRESS64 so we have some chance to see what is actually
going on. Tested on the FVP fast model.

Some versions of Exynos5 supports High-Speed I2C,
on few interfaces, this change allows support this.
The new flag is: PINMUX_FLAG_HS_MODE

This patch modify i2c nodes in exynos4.dtsi with:
- adding proper interrupts arrays for each i2c node,
which allows to decode periph id
- add reg address for each i2c node for i2c driver internal use

Rather than assuming that the chip offset length is 1, allow it to be
provided. This allows chips that don't use the default offset length to
be used (at present they are only supported by the command line 'i2c'
command which sets the offset length explicitly).

In f0c3a6c we stopped setting gd in board_init_f, but later had to
revert to due problems on certain platforms. As davinci does not look
to have these problems, we can drop the setting here and rely upon
crt0.S to do it.

On the DRA72x (J6Eco) EVM one PMIC SMPS is powering three SoC
core rails. This concept of using one SMPS to supply multiple
core domains (in various, although limited combinations, per
primary device use case) has now become common and is used by
many customer J6/J6Eco designs; it is supported by a number of
corresponding PMIC OTP versions.
This patch implements correct operation of the core voltages
scaling routine by ensuring that each SMPS that is supplying
more than one domain shall be written only once, and with the
highest voltage of those fused in the SoC (or of those defined
in the corresponding header if fuse read is disabled or fails)
for the power rails belonging to the group.
The patch also replaces some PMIC-related magic numbers with
the appropriate definitions. The default OPP_NOM voltages for
the DRA7xx SoCs are updated as well, per the latest DMs.
