Jump into full u-boot mode if a 'c' character is received on the uart.
We need to adjust the spl bss/malloc area to not overlap with the
loadaddr of the kernel (sdram + 32k), so move it past u-boot instead.
For raw mmc, we store the kernel parameter area in the free space after
the MBR (if used). For nand, we use the last sector of the partition
reserved for u-boot.
This also enables the spl command in the full u-boot so the kernel
parameter area snapshot can be created.

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
boards.

The AM33xx emif4/ddr support closely matches what is need to support
TI814x except that TI814x has two EMIF instances. Refactor all the
emif4 helper calls and the config_ddr() init function to use an
additional instance number argument.

Enable DDR PHY dynamic power down bit, which enables
powering down the IO receiver when not performing read.
This also helps in reducing overall power consumption in
low power states (suspend/standby).

We add USB (RNDIS gadget) SPL support as a separate target. We need to

This adds necessary config options and a new build target,
am335x_evm_usbspl, to enable usb booting and fixes board_eth_init()
function to take into account that we may have USB ether support in SPL
now. This uses the same MAC for both cpsw and USB, in order to match
ROM behavior.
The usbspl build target does not contain UART SPL, CPSW SPL or extra
environment settings, so that we may fit within our binary size
constraint.

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.
