In the current u-boot, the device pin multiplexing and clock
initialisation needs to be early during the boot process and before
board_init() is called. U-boot is currently crashing on this board
because this is not being done early enough. Therefore, add a s_init()
function for the omap5912-osk board to do this.
Also fix the stack pointer so that it is pointing to the end of the
internal RAM and not the beginning as this was also causing the device
to crash.

The omap5912-osk board is using a RAM based address as the linker
location for code. This is causing several problems when attempting
to run the latest u-boot code base on this board from flash. Update
the default linker location for code to be in NOR flash at address
0x00000000.
The omap5912-osk board only has 32MB of RAM and so fix the comment
in the omap5912-osk config.mk file as well.

The size of the DRAM for the omap5912-osk board is getting setup in the
dram_init() function. However, for the current u-boot release this is
too late and needs to be done in dram_init_banksize(). Therefore, add
a dram_init_banksize() function for the omap5912-osk board and setup the
DRAM size there.

The omap2420-h4 board is using a RAM based address as the linker
location for code. This is causing several problems when attempting
to run the latest u-boot code base on this board from flash. Update
the default linker location for code to be in NOR flash. Please note
that OMAP maps the NOR flash to address 0x08000000 by default and so
use this as the default address for the NOR flash.
Also remove legacy code that attempts to calculate where in flash the
sdata structure, that holds the memory interface configuration data,
is located. By changing the default linker location for code to flash
this is no longer necessary.

Currently, omap3_dss_panel_config() sets gfx_format to a value that is hardcoded
in the code. This forces anyone who wants to use a different gfx_format to make
adjustments after calling omap3_dss_panel_config(). This could be avoided if the
value of gfx_format were parameterized as input for omap3_dss_panel_config().
Make gfx_format a field in struct panel_config, and update existing structs to
set this field to the value that was originally hard coded.

This patch extends the am335x_evm board for the AM335x IDK.
The IDK board uses MII for the ethernet phy (same as
Beaglebone board) and MMC0 for storage (but without
card detect line).
The IDK uses UART3 for console. So u-boot must be build
with CONFIG_SERIAL4 and CONFIG_CONS_INDEX=4 or for
the am335x_evm_uart3 board configuration as introduced
by Andrew Bradfords recent patch series "am33xx: Enable
UART {1,2,3,4,5}...". When using the IDK with console on UART0,
those patches are not required. In this case the board
slightly needs to be modified.

This patch adds support for networking in SPL. Some devices are
capable of loading SPL via network so it makes sense to load the
main U-Boot binary via network too. This patch tries to use

is increased significantly. No effort was done to decouple network
