* NAND boot: MPC8313ERDB supportScott Wood2008-08-12-107/+45
| | | | | | | | | Note that with older board revisions, NAND boot may only work after a power-on reset, and not after a warm reset. I don't have a newer board to test on; if you have a board with a 33MHz crystal, please let me know if it works after a warm reset. Signed-off-by: Scott Wood <scottwood@freescale.com>
* PPC: Create and use CONFIG_HIGH_BATSBecky Bruce2008-06-03-3/+3
| | | | | | | | | | | Change all code that conditionally operates on high bat registers (that is, BATs 4-7) to look at CONFIG_HIGH_BATS instead of the myriad ways this is done now. Define the option for every config for which high bats are supported (and enabled by early boot, on parts where they're not always enabled) Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
* lib_ppc: Revert "Make MPC83xx one step closer to full relocation."Kim Phillips2008-04-25-7/+4
| | | | | | | | This reverts commit 70431e8a7393b6b793f77957f95b999fc9a269b8 which has proven problematic getting right from the start at least on 83xx and 4xx. Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
* Make MPC83xx one step closer to full relocation.Joakim Tjernlund2008-03-28-4/+7
| | | | | | | | Remove a few absolute references to CFG_MONITOR_BASE for ppc/mpc83xx and use GOT relative reference. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>

* [ppc] Fix build breakage for all non-4xx PowerPC variants.Rafal Jaworowski2007-06-22-2/+2
| | | | | - adapt to the more generic EXCEPTION_PROLOG and CRIT_EXCEPTION macros - minor 4xx cleanup
* mpc83xx: Put the version (and magic) after the HRCW.Jerry Van Baren2007-03-02-12/+16
| | | | | | | Put the version (and magic) after the HRCW. This puts it in a fixed location in flash, not at the start of flash but as close as we can get. Signed-off-by: Jerry Van Baren <vanbaren@cideas.com>
* mpc83xx: Replace CFG_IMMRBAR with CFG_IMMRTimur Tabi2006-11-03-8/+8
| | | | | | | Replace all instances of CFG_IMMRBAR with CFG_IMMR, so that the 83xx tree matches the other 8xxx trees. Signed-off-by: Timur Tabi <timur@freescale.com>
* mpc83xx: Fix the incorrect dcbz operationDave Liu2006-11-03-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 834x rev1.x silicon has one CPU5 errata. The issue is when the data cache locked with HID0[DLOCK], the dcbz instruction looks like no-op inst. The right behavior of the data cache is when the data cache Locked with HID0[DLOCK], the dcbz instruction allocates new tags in cache. The 834x rev3.0 and later and 8360 have not this bug inside. So, when 834x rev3.0/8360 are working with ECC, the dcbz instruction will corrupt the stack in cache, the processor will checkstop reset. However, the 834x rev1.x can work with ECC with these code, because the sillicon has this cache bug. The dcbz will not corrupt the stack in cache. Really, it is the fault code running on fault sillicon. This patch fix the incorrect dcbz operation. Instead of CPU FP writing to initialise the ECC. CHANGELOG: * Fix the incorrect dcbz operation instead of CPU FP writing to initialise the ECC memory. Otherwise, it will corrupt the stack in cache, The processor will checkstop reset.

* mpc83xx: Add support for variable flash memory sizes on 83xx systemsTimur Tabi2006-11-03-8/+21
| | | | | | | | | CHANGELOG: * On 83xx systems, use the CFG_FLASH_SIZE macro to program the LBC local access window registers, instead of using a hard-coded value of 8MB. Signed-off-by: Timur Tabi <timur@freescale.com>
