* Invalidate INIT_RAM TLB mappingsAndy Fleming2008-02-27-0/+11
| | | | | | | | | | | | | | | Commit 0db37dc... (and some others) changed the INIT_RAM TLB mappings to be unguarded. This collided with an existing "bug" where the mappings for the INIT_RAM were being kept around. This meant that speculative loads to those addresses were succeeding in the TLB, and going out to the bus, where they were causing an exception (there's nothing at that address). The Flash code was coincidentally causing such a speculative load. Rather than go back to mapping the INIT RAM as guarded, we fix it so that the entries for the INIT_RAM are invalidated. Thus the speculative loads will fail in the TLB, and have no effect. Signed-off-by: Andy Fleming <afleming@freescale.com>

| * 86xx: Convert sbc8641d to use libfdt.Jon Loeliger2008-02-18-66/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the proper fix for a missing closing brace in the function ft_cpu_setup() noticed by joe.hamman <at> embeddedspecialties.com. The ft_cpu_setup() function in mpc8641hpcn.c should have been removed earlier as it was under the obsolete CONFIG_OF_FLAT_TREE, but was missed. Only, the sbc8641d was nominally still using it. It all got ripped out, and the funcality that was in ft_board_setup() was refactored to remove the CPU portions into the new file cpu/mpc86xx/fdt.c instead. Make sbc8641d use this now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current ndfc HW ECC implementation swaps the first two ECC bytes. But the 4xx NDFC already uses the SMC (Smart Media Card) ECC ordering, so this swapping in the HW ECC driver is bogus. This patch fixes this problem and now really uses the SMC ECC byte order.

This is not always true, and indeed on the ATNGW100, the refresh rate should really be 7.81 us. Add a refresh_period member to struct sdram_info and initialize it properly for both ATSTK1000 and ATNGW100. Out-of-tree boards will panic() until the refresh_period member is updated properly.

Before this work, we used another OneNAND IPL called X-Loader based on open source. With this work, we can build the oneboot.bin image without other program. The build sequence is simple. First, it compiles the u-boot.bin Second, it compiles OneNAND IPL Finally, it becomes the oneboot.bin from OneNAND IPL and u-boot.bin The mechanism is similar with NAND boot except it boots from itself. Another thing is that you can only use the OneNAND IPL only to work other bootloader such as RedBoot and so on. Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
