omap3/mem.c: remove unused defines

These GPMC_CS defines are a leftover from prior gpmc_init(). Commit 187af954
removed the need for these definitions but missed to remove them.

OMAP: include sys_proto.h from boot-common

Include asm/arch/sys_proto.h for gpmc_init prototype.
Without this we get a warning while building for AM335x.

am33xx: NAND support

TI AM33XX has the same GPMC controller as OMAP3 so we could just use the
existing omap_gpmc driver. This patch adds adds required

am33xx: add ELM support

AM33XX has Error Location Module (ELM) that can be used in conjuction
with GPMC controller to implement BCH codes fully in hardware.
This code is mostly taken from arago tree.

omap_gpmc: BCH8 support (ELM based)

This patch adds support for BCH8 error correction code to omap_gpmc
driver. We use GPMC to generate codes/syndromes but we need ELM to find
error locations from given syndrome.

am33xx_spl_bch: simple SPL nand loader for AM33XX

AM33XX with BCH8 can't work with nand_spl_simple correctly
because custom read_page implementation is required for proper
syndrome generation.

This simple driver mostly duplicates nand_spl_simple but has
nand_read_page changed to suit our needs.

Pass sdrc timing values through board_sdrc_timings structure

Instead of passing individual registers by value to board_get_mem_timings,
pass a board_mem_timings structure pointer for the board files to fill in.
Pass same structure pointer to write_sdrc_timings.  This saves about
90 bytes of space in SPL.

OMAP3 SPI : Fixed bugs related to SPI transfer

Added posted writes (read after writes) to effect the
change immediately for channel confiuration and channel
enable register

Disable the channel to purge receieve data in TX_ONLY
mode transfer otherwise rx data will get affected by
the next immediate RX_ONLY mode transfer

Wait for the EOT bit to be set after last byte has been
loaded to TX shift register in the the TX_ONLY mode.This
ensures TX data has been completely shifted out

Disable the channel in RX_ONLY mode before reading the
last data from  RXX register to prevent the SPI slave
to transmit next word
