Currently MX6 SPL DDR initialization hardcodes the REF_SEL and
REFR fields of the MDREF register as 1 and 7, respectively for
DDR3 and 0 and 3 for LPDDR2.Looking at the MDREF initialization done via DCD we see that
boards do need to initialize these fields differently:$ git grep 0x021b0020 board/

with the Ethernet initialization.As per the AR8035 datasheet:
"For a reliable power on reset, suggest to keep asserting the reset
low long enough (10ms) to ensure the clock is stable and clock-to-reset
1ms requirement is satisfied."So do as suggested and keep the reset low for 10ms.
Also add a 100us delay after deasserting the reset line
to guarantee that the PHY ID can be read correctly and the Atheros
PHY can be loaded as per Troy Kisky's suggestion.Signed-off-by: Fabio Estevam

To i.MX6, DDR3 and LPDDR2 is supported, so rename function mx6_dram_cfg
to mx6_ddr3_cfg and the original mx6_dram_cfg function only is a wrapper.
The new reimplemented function mx6_dram_cfg only invokes mx6_ddr3_cfg
when ddr_type is for DDR3. Later we can use ddr_type to initialize
MMDC for LPDDR2.Initialize ddr_type for different boards which enable SPL.

mx6cuboxi sometimes fails to recognize the Ethernet PHY:
Net: Phy 0 not found
The explanation for this behavior comes from from Rabeeh Khoury:
"The LED_ACT pin on the carrier-one boards had a pull down that
forces the phy address to 0x0; where on CuBox-i and the production
HummingBoard that pin is connected directly to LED that depending
on the pull down strength of the LED it might be sampled as '0' or '1' thus
the phy address might appear as either address 0x0 or 0x4.""This is AR8035 implementation; in reset stage the LED pin is configured as
input, and pull up/down does matter. In this case it configures the PHY
address.After reset is deasserted the same LED pin becomes output and then
according to the previous pull/up it should be active high/low"One way to properly fix this behavior is to place external pull-up/down
resistors in the LED line, but from a software standpoint we can fix it
by telling phy_find_by_mask() to scan the PHY at addresses
0x0 and 0x4.Reported-by: Vagrant Cascadian

Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected

SYS_CPU in the corresponding Kconfig file is removed.Also, it removes redundant "string" type in some Kconfig files.

information from it.The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect

This commit adds:
- arch/${ARCH}/Kconfig
provide a menu to select target boards
- board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
set CONFIG macros to the appropriate values for each board
- configs/${TARGET_BOARD}_defconfig
default setting of each board(This commit was automatically generated by a conversion script
based on boards.cfg)In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.Signed-off-by: Masahiro Yamada

There is no need to keep iomuxc_base_regs structure as it serves the exact same
purpose of the iomuxc structure, which is to provide access to the GPR
registers.The additional fields of iomuxc_base_regs are not used. Other advantage of
'iomuxc' is that it has a shorter name and the variable declarations can fit
into a single line.So remove iomuxc_base_regs structure and use iomuxc instead.
