[U-Boot] [PATCH 0/5] ARM: keystone2: Build images by default

[Lokesh Vutla]

Currently we need to build each image(u-boot.uart, u-boot-nand.gph,
u-boot-spi.gph) separately for all keystone2 platforms.

This series does the following:
- Move SP to end of u-boot section so that u-boot.bin can be used as
  build target for uart boot.
- Renames u-boot-nand.gph to MLO so that the same image can be used
  for NAND and SD boots.
- Includes these images in config.mk so that these images are built
  automatically upon calling make.

Now the updated build targets are as below:
Uart:	u-boot.bin
SPI:	u-boot-spi.gph
NAND:	MLO
SD:	MLO

Testing:

SPI boot: http://pastebin.ubuntu.com/12106315/
NAND boot: http://pastebin.ubuntu.com/12106368/

[U-Boot] [PATCH 1/5] ARM: keystone2: configs: Move SP to end of u-boot section

[Lokesh Vutla]

Currently u-boot stack is defined at the beginning of MSMC RAM.
This is a problem for uart boot mode as ROM downloads directly to
starting of MSMC RAM.
Fixing it by moving stack to the end of u-boot section and shifting
SYS_TEXT_BASE to the start of MSMC RAM.
Updated division of MSMC RAM is shown below:
	-----------------------------------------
	|		|	|		|
	| U-Boot text	|U-Boot	| SPL text	|
	| download	| Stack	| Download +	|
	|		|	| SPL_BSS +	|
	|		|	| SPL_STACK	|
	-----------------------------------------
	[1]		[2]	[3]		[4]

[1] SYS_TEXT_BASE (Start of MSMC RAM)
[2] SPL_TEXT_BASE - GBL_DATA_SIZE
[3] SPL_TEXT_BASE
[4] END of SPL

[1] + [2] is at least 1M on all platforms, so no chance of overlap.

[U-Boot] [PATCH 2/5] ARM: keystone2: move the custom build rules out to keystone specific makefile

[Lokesh Vutla]

From: Nishanth Menon <nm@ti.com>

Keystone has build rules introduced by commit ef509b9063fb7 ("k2hk: add
support for k2hk SOC and EVM") and commit 0e7f2dbac6ead ("keystone: add
support for NAND gpheader image").

These are not reused by other platforms for the build, hence there is no
clear benefit is maintaining them in the generic makefile as a build
target. move these to the keystone specific make option

Original idea of using config.mk by Lokesh Vutla <lokeshvutla@ti.com>

[U-Boot] [PATCH 3/5] ARM: keystone2: Rename u-boot-nand.gph to MLO

[Lokesh Vutla]

NAND boot mode, ROM expects an image with a gp header in the
beginning and an 8bytes filled with zeros at the end. The same is
true for SD boot on K2G platforms but the file name should be MLO.

Renaming u-boot-nand.gph to MLO, so that same image can be used for
NAND and SD boots. And also not including all the u-boot only images
under CONFIG_SPL_BUILD.

[U-Boot] [PATCH 4/5] ARM: keystone2: Build MLO by default

[Lokesh Vutla]

MLO(NAND/MMC boot image), is used for all the ks2 platforms.
Enabling it in config.mk so that these images will be automatically
built upon calling make. u-boot-spi.gph is already the build target,
so not including here.

This change is great. Now that this patch is done, I might like to see
the documentation of uart download added in as well - the sequence is
not really straight forward without documentation to follow
