Browse Source 
When SPL_NAND_SUNXI option is selected in config, set some configuration
options for sunxi NAND.

This commit also introduces the configurable options in Kconfig.

@ -85,6 +85,46 @@ config SPL_NAND_DENALI
This is a small implementation of the Denali NAND controller
for use on SPL.
config SPL_NAND_SUNXI
bool "Support for NAND on Allwinner A20 in SPL"
depends on MACH_SUN7I
---help---
Enable support for NAND. This option allows SPL to read from
sunxi NAND using DMA transfers.
Depending on the NAND chip, values like ECC strength and page sizes
have to be configured.
config NAND_SUNXI_SPL_SYNDROME_PARTITIONS_END
hex "Size of syndrome partitions in sunxi NAND"
default 0x400000
depends on SPL_NAND_SUNXI
---help---
End address for boot partitions on NAND. Those partitions have a
different random seed that has to match the sunxi BROM setting.
config NAND_SUNXI_SPL_ECC_STRENGTH
int "ECC Strength for sunxi NAND"
default 40
depends on SPL_NAND_SUNXI
---help---
ECC strength used by the sunxi NAND SPL driver. This is specific to the
chosen NAND chip and has to match the value used by the sunxi BROM.
config NAND_SUNXI_SPL_ECC_PAGE_SIZE
hex "ECC page size for sunxi NAND"
default 0x400
depends on SPL_NAND_SUNXI
---help---
ECC page size used by the sunxi NAND SPL driver for syndrome partitions.
This setting has to match the value used by the sunxi BROM.
config NAND_SUNXI_SPL_PAGE_SIZE
hex "Page size for sunxi NAND"
default 0x2000
depends on SPL_NAND_SUNXI
---help---
Page size of the NAND flash used by the sunxi NAND SPL driver. This is
specific to the chosen NAND chip.
