7234f215cc ARM: keystone2: Define board_fit_config_name_match for Keystone 2 boards
Now with support for U-boot runtime dtb selection each board needs to
define board_fit_config_name_match so U-boot can determine what the
correct dtb is within the FIT blob.

5f48da9a98 ARM: k2g: Define embedded_dtb_select for runtime DTB selection in U-boot
For K2G, runtime DTB selection utilizes the embedded_dtb_select function.
Therefore, define the function which will perform a EEPROM read and then
retries selecting the correct dtb now that it can detect which board its
on. For other Keystone devices use an empty function since they will still
use the embedded FIT functionality but their FIT will only contain a single
dtb.

Most production K2G boards do not have their EEPROM programmed. Therefore,
perform a test to verify a K2G GP is currently being used and if it is then
set the values normally set by a EEPROM read.

ee3c6532be ARM: keystone2: Add support for getting external clock dynamically
One some keystone2 platforms like K2G ICE, there is an option

driver assumes it is always 24MHz. Add support for getting

d5abcf94c7 ti: boot: Register the MMC controllers in SPL in the same way as in u-boot
To keep a consistent MMC device mapping in SPL and in u-boot, let's
register the MMC controllers the same way in u-boot and in the SPL.
In terms of boot time, it doesn't hurt to register more controllers than
needed because the MMC device is initialized only prior being accessed for
the first time.
Having the same device mapping in SPL and u-boot allows us to use the
environment in SPL whatever the MMC boot device.

8efc243741 ARM: keystone2: use detected ddr3a size
Because KS2 u-boot works in 32 bit address space the existing ram_size
global data field cannot be used. The maximum, which the get_ram_size()
can detect is 2GB only. The ft_board_setup() needs the actual ddr3 size
to fix up dtb.

This commit introduces the ddr3_get_size() which uses SPD data to
calculate the ddr3 size. This function replaces the "ddr3_size"
environment variable, which was used to get the SODIMM size.

For platforms, which don't have SODIMM with SPD and ddr3 is populated to
a board a simple ddr3_get_size function that returns ddr3 size has to be
implemented. See hardware-k2l.h

e895a4b06f fdt: Allow ft_board_setup() to report failure
This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.

Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.

Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

An ecc_test environment variable is added for ECC testing.
If ecc_test is set to 0, a detection of 2-bit error will reset
the device, if ecc_test is set to 1, 2-bit error detection
will not reset the device, user can still boot the kernel to

69a3b81141 ARM: keystone: clock: add support for K2E SoCs
For K2E and K2L SoCs clock output from PASS PLL has to be enabled
after NETCP domain and PA module are enabled. So create new function
for that and call it after PA module is enabled.

497e9e0321 net: keystone_net: remove redundant code from keystone_net.c
Remove unused tx_send_loop variable.

Removes duplicated get_link_status() call from the
keystone2_eth_send_packet().

The emac_gigabit_enable() is called at opening Ethernet and there is no
need to enable it on sending each packet. So remove that call
from keystone2_eth_send_packet() as well.

The calling of power/clock up functions are mostly the responsibility
of SoC/board code, so move these functions to appropriate place.

0935cac685 net: keystone_net: move header file from arch to ti-common
The header file for the driver should be in correct place.
So move it to "arch/arm/include/asm/ti-common/keystone_net.h"
and correct driver's external dependencies. At the same time
align and correct some definitions.

a79c911f35 ks2_evm: readme: align according to actual sources
Update readme file for Keystone II EVM boards to actual sources.
Also correct some typos. For now the Edison evaluation board is
added, README for K2E is mostly the same, so update README to
contain information also for K2E evm. Rename file to README as
it contains information for all keystone evm boards.

6c343825dd ARM: keystone: ddr3: workaround for ddr3a/3b memory issue
This patch implements a workaround to fix DDR3 memory issue.
The code for workaround detects PGSR0 errors and then preps for
and executes a software-controlled hard reset.In board_early_init,
where logic has been added to identify whether or not the previous
reset was a PORz. PLL initialization is skipped in the case of a
software-controlled hard reset.

461be2f96e kconfig: remove redundant "string" type in arch and board Kconfigs
Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME}
are specified in arch/Kconfig.

We can delete the ones in arch and board Kconfig files.

This commit can be easily reproduced by the following command:

find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e '
/config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ {
    N
    s/\n[[:space:]]*string//

Becuase the board select menu in arch/arm/Kconfig is too big,
move the Keystone board select menu to keystone/Kconfig.

Move also common settings (CONFIG_SYS_CPU="armv7" and
CONFIG_SYS_SOC="keystone").

93d4334f7f Add board MAINTAINERS files
We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
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
relevant information for a board into a single place.

TODO:
Modify get_maintainer.pl to scan multiple MAINTAINERS files.

dd84058d24 kconfig: add board Kconfig and defconfig files
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/.
