* 85xx: MP Boot Page Translation updatePeter Tyser2009-10-27-31/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change has 3 goals: - Have secondary cores be released into spin loops at their 'true' address in SDRAM. Previously, secondary cores were put into spin loops in the 0xfffffxxx address range which required that boot page translation was always enabled while cores were in their spin loops. - Allow the TLB window that the primary core uses to access the secondary cores boot page to be placed at any address. Previously, a TLB window at 0xfffff000 was always used to access the seconary cores' boot page. This TLB address requirement overlapped with other peripherals on some boards (eg XPedite5370). By default, the boot page TLB will still use the 0xfffffxxx address range, but this can be overridden on a board-by-board basis by defining a custom CONFIG_BPTR_VIRT_ADDR. Note that the TLB used to map the boot page remains in use while U-Boot executes. Previously it was only temporarily used, then restored to its initial value. - Allow Boot Page Translation to be disabled on bootup. Previously, Boot Page Translation was always left enabled after secondary cores were brought out of reset. This caused the 0xfffffxxx address range to somewhat "magically" be translated to an address in SDRAM. Some boards may not want this oddity in their memory map, so defining CONFIG_MPC8xxx_DISABLE_BPTR will turn off Boot Page Translation after the secondary cores are initialized. These changes are only applicable to 85xx boards with CONFIG_MP defined. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | U-boot for Marvell Kirkwood boards no longer work after the EABI changes introduced in commit f772acf8a584067033eff1e231fcd1fb3a00d3d9. This turns out to be caused by a stack alignment issue. The armv5te instructions ldrd/strd instructions require 8-byte alignment to work properly (otherwise undefined behavior).

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | v7_flush_dcache_all, because it depends on omap ROM code is not generic. Rename the function to 'invalidate_dcache' and move it to the omap cpu directory. Collect the other omap cache routines l2_cache_enable and l2_cache_disable with invalide_dcache into cache.S. This means removing the old cache.c file that contained l2_cache_enable and l2_cache_disable. The conversion from cache.c to cache.S was done most through disassembling the uboot binary. The only significant change was to change the comparision for the return of get_cpu_rev from cmp r0, #0 beq earlier_than_label Which was lost information to cmp r0, #CPU_3XX_ES20 blt earlier_than_label The paths through the enable routine were verified by adding an infinite loop and seeing the hang. Then removing the infinite loop and seeing it continue. The disable routine is similar enough that it was not tested with this method. Run tested by cold booting from nand on beagle and zoom1.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When U-Boot is relocated from flash to RAM pointers are modified accordingly. However, pointers initialzed with NULL values should not be modified so that they maintain their intended NULL value. If the BSS segment is linked at address 0 its address will not be updated as necessary during relocation. This is a temporary workaround. The end goal is to add support to U-Boot to dynamically locate the BSS at an arbitrary address at runtime. When the ability to fixup the BSS inteligently is added, this workaround can be removed and the 85xx link script can put the BSS at a fixed address at link time.

* ppc/p4080: CoreNet platfrom style secondary core releaseKumar Gala2009-09-24-3/+65
| | | | | | | | | The CoreNet platform style of bringing secondary cores out of reset is a bit different that the PQ3 style. Mostly the registers that we use to setup boot translation, enable time bases, and boot release the cores have moved around. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* ppc/p4080: CoreNet platfrom style CCSRBAR settingKumar Gala2009-09-24-18/+54
| | | | | | | | On CoreNet based platforms the CCSRBAR address is split between an high & low register and we no longer shift the address. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Scott Wood <scottwood@freescale.com>
