Currently same value is programmed for all ioregs. This is not
the case for all SoC's like AM4372. So adding a structure for ioregs
and updating in all board files. And also return from config_cmd_ctrl()
and config_ddr_data() functions if data is not passed.Signed-off-by: Lokesh Vutla

Based on the definitive guide to EMIF configuration[1] certain registers
that we have been modifying (and are documented registers) should be
left in their reset values rather than modified. This has been tested
on AM335x GP EVM and Beaglebone White.[1]: http://processors.wiki.ti.com/index.php/AM335x_EMIF_Configuration_tips

Since 2bf36ac638ab2db9f0295aa47064976eeebf80c1 the BD ram address is
not hardcoded inside cpsw driver any more. Platforms have to supply
their bd_ram_ofs in the platform data to the driver. This commit does
this for pcm051 and igep0033 boards.Tested-by: Enric Balletbo i Serra

We defined PHYS_DRAM_1 to 0x80000000 (start of DRAM) and then used this
for CONFIG_SYS_SDRAM_BASE. But then we kept on referencing PHYS_DRAM_1
in other places. Change to directly setting CONFIG_SYS_DRAM_BASE and
then using that name in code.Signed-off-by: Tom Rini

IGEP boards now have Device Tree support in the mainline
kernel. To boot an IGEP board using a DT, a uEnv.txt plain
text file could be used to define a custom uenvcmd that will
be run by the default boot command.It is more convenient to change the default boot command to
allow loading a FDT if it is stored in the boot dir of the
rootfs uSD/MMC partition.If no FDT is found then the defaul command tries to boot a
zImage without a DT using legacy boot.Signed-off-by: Javier Martinez Canillas

We need to call the save_omap_boot_params function on am33xx/ti81xx and
other newer TI SoCs, so move the function to boot-common. Only OMAP4+
has the omap_hw_init_context function so add ifdefs to not call it on
am33xx/ti81xx. Call save_omap_boot_params from s_init on am33xx/ti81xx

This patch adds an GPIO LED boot status for IGEP boards.
The GPIO LED used is the red LED0 while the Linux kernel
uses the green LED0 as the boot status.By using different GPIO LEDs, the user can know in which
step of the boot process the board currently is.Signed-off-by: Javier Martinez Canillas

Even when the IGEPv2 board and the IGEP Computer-on-Module
are different from a form factor point of view, they are
very similar in the fact that share many components and how
they are wired.So, it is possible (and better) to have a single board file
for both devices and just use the CONFIG_MACH_TYPE to make
a differentiation between each board when needed.This change avoids code duplication by removing 298 lines of
code and makes future maintenance easier.Signed-off-by: Javier Martinez Canillas

This is rework on config files of IGEP-based boards with the aim to remove
duplicated code to be more maintainable. Basically this patch creates a
common configuration file for both boards and only sets the specific option
in the board config file.On board files the hardcored mach type was replaced in favour of using the
CONFIG_MACH_TYPE option.More than 200 duplicated lines have been deleted.

Add parameters to the OMAP MMC initialization function so the board can
mask host capabilities and set the maximum clock frequency. While the
OMAP supports a certain set of MMC host capabilities, individual boards
may be more restricted and the OMAP may need to be configured to match
the board. The PRG_SDMMC1_SPEEDCTRL bit in the OMAP3 is an example.Signed-off-by: Jonathan Solnit

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.Signed-off-by: Sebastien Carlier
