This patch adds support for NAND device connected to GPMC chip-select on
following AM43xx EVM boards.
am437x-gp-evm: On this board, NAND Flash signals are muxed with eMMC, thus at a
time either eMMC or NAND can be enabled. Selection between eMMC and NAND is
controlled by:
(a) Statically using Jumper on connecter (J89) present on board.
(a) If Jumper on J89 is NOT used, then selection can be dynamically controlled
by driving SPI2_CS0[MUX_MODE=GPIO] pin via software:
SPI2_CS0 == 0: NAND (default)
SPI2_CS0 == 1: eMMC
am43x-epos-evm: On this board, NAND Flash control lines are muxed with QSPI,
Thus only one of the two can be used at a time. Selection is controlled by:
(a) Dynamically driving following GPIO pin from software
GPMC_A0(GPIO) == 0 NAND is selected (default)
NAND device (MT29F4G08AB) on these boards has:
- data-width=8bits
- blocksize=256KB
- pagesize=4KB
- oobsize=224 bytes
For above NAND device, ROM code expects the boot-loader to be flashed in BCH16
ECC scheme for NAND boot, So by default BCH16 ECC is enabled for AM43xx EVMs.
