* NAND boot: MPC8536DS supportMingkai Hu2009-09-301-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MPC8536E can support booting from NAND flash which uses the image u-boot-nand.bin. This image contains two parts: a 4K NAND loader and a main U-Boot image. The former is appended to the latter to produce u-boot-nand.bin. The 4K NAND loader includes the corresponding nand_spl directory, along with the code twisted by CONFIG_NAND_SPL. The main U-Boot image just like a general U-Boot image except the parts that included by CONFIG_SYS_RAMBOOT. When power on, eLBC will automatically load from bank 0 the 4K NAND loader into the FCM buffer RAM where CPU can execute the boot code directly. In the first stage, the NAND loader copies itself to RAM or L2SRAM to free up the FCM buffer RAM, then loads the main image from NAND flash to RAM or L2SRAM and boot from it. This patch implements the NAND loader to load the main image into L2SRAM, so the main image can configure the RAM by using SPD EEPROM. In the first stage, the NAND loader copies itself to the second to last 4K address space, and uses the last 4K address space as the initial RAM for stack. Obviously, the size of L2SRAM shouldn't be less than the size of the image used. If so, the workaround is to generate another image that includes the code to configure the RAM by SPD and load it to L2SRAM first, then relocate the main image to RAM to boot up.

* 85xx: Introduce CONFIG_SYS_PCI*_IO_VIRT for FSL boardsKumar Gala2009-01-231-1/+1
| | | | | | | | | Introduce a new define to seperate out the virtual address that PCI IO space is at from the physical address. In most situations these are mapped 1:1. However any code accessing the bus should use VIRT. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Andy Fleming <afleming@freescale.com>

* 85xx: separate FLASH BASE virtual from physical addressKumar Gala2009-01-231-1/+1
| | | | | | | | | | Added a CONFIG_SYS_FLASH_BASE_PHYS for use as the physical address and maintain CONFIG_SYS_FLASH_BASE as the virtual address of the flash. This allows us to deal with 36-bit phys on these boards in the future. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Andy Fleming <afleming@freescale.com>

* NAND: Add NAND support for MPC8536DS boardJason Jin2008-10-311-0/+5
| | | | | | | | | | This patch defines 1M TLB&LAW size for NAND on MPC8536DS, assigns 0xffa00000 for CONFIG_SYS_NAND_BASE and adds other NAND supports in config file. It also moves environment(CONFIG_ENV_ADDR) outside of u-boot image.

* 85xx: Improve flash remapping on MPC8572DS & MPC8536DSKumar Gala2008-10-181-1/+1
| | | | | | | | Changing the flash from cacheable to cache-inhibited was taking a significant amount of time due to the fact that we were iterating over the full 256M of flash. Instead we can just flush the L1 d-cache and invalidate the i-cache. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
