Signed-off-by: Wenyou Yang wenyou.yang@atmel.com
The patch is based on the following patches sent in mailing list. [PATCH] gpio: atmel: Add the PIO4 driver support [PATCH] arm: at91: Change the Chip ID registers' addresses [PATCH v3] mmc: atmel: Add atmel sdhci support [PATCH v2] arm: at91: clock: Add the generated clock support
Changes in v4: 1./ remove __weak attribute for has_lcdc() added in v3. 2./ remove unused goto err_exit.
Changes in v3: 1./ change defines-->definitions for more clearly in asm/arch/sama5d2.h. 2./ remove unused cpu_is_sama5d2x() macros. 3./ fix spelling error "adress". 4./ add __weak attribute for has_lcdc(). 5./ remove SPL configs.
Changes in v2: 1./ re-order SAMA5D2 statements alphabetically. 2./ remove redundant "Unknown CPU type". 3./ rework sama5d2's macros. 4./ remove some #ifdef before functions. 5./ move CONFIG_CMD_SF to Kconfig. 6./ remove NAND macros from config file. 7./ CONFIG_BOOTCOMMAND for sf uses defines in at91-sama5_common.h.
