* 85xx: Additional fixes and cleanup of MP codeKumar Gala2008-04-29-2/+7
| | | | | | | | | | | | | | | | | * adjust __spin_table alignment to match ePAPR v0.94 spec * loop over all cpus when determing who is up. This fixes an issue if the "boot cpu" isn't core0. The "boot cpu" will already be in the cpu_up_mask so there is no harm * Added some protection in the code to ensure proper behavior. These changes are explicitly needed but don't hurt: - Added eieio to ensure the "hot word" of the table is written after all other table updates have occurred. - Added isync to ensure we don't prefetch loading of table entries until we a released These issues we raised by Dave Liu.

| * ppc4xx: Pass PCIe root-complex/endpoint configuration to Linux via the fdtStefan Roese2008-04-25-0/+42
| | | | | | | | | | | | | | | | | | | | The PCIe root-complex/endpoint setup as configured via the "pcie_mode" environment variable will now get passed to the Linux kernel by setting the device_type property of the PCIe device tree node. For normal root- complex configuration it will keep its defaults value of "pci" and for endpoint configuration it will get changed to "pci-endpoint". Signed-off-by: Stefan Roese <sr@denx.de>

| * | ARM: Davinci: Fix DM644x timer overflow handling and cleanupDirk Behme2008-04-22-47/+23
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix ARM based DaVinci DM644x timer overflow handling and cleanup timer code. Changes: - Remove *_masked() functions as noted by Wolfgang - Adapt register naming to recent TI spec (sprue26, March 2007) - Fix reset_timer() handling - As reported by Pieter [1] the overflow fix introduced a delay of factor 16 (e.g 2 seconds became 32). While the overflow fix is basically okay, it missed to divide udelay by 16, too. Fix this. [1] http://article.gmane.org/gmane.comp.boot-loaders.u-boot/38179 - Remove software division of timer count value (DIV(x) macro) and do it in hardware (TIM_CLK_DIV). Many thanks to Troy Kisky <troy.kisky@boundarydevices.com> and Pieter Voorthuijsen <pieter.voorthuijsen@Prodrive.nl> for the hints & testing! Patch is compile tested with davinci_dvevm & sonata & schmoogie configuration and tested by Pieter on DaVinci EVM hardware.

| * Fix calculation of I2C clock for some 85xx chipsTimur Tabi2008-04-18-1/+30
| | | | | | | | | | | | | | | | | | | | | | Some 85xx chips use CCB as the base clock for the I2C. Some use CCB/2, and some use CCB/3. There is no pattern that can be used to determine which chips use which frequency, so the only way to determine is to look up the actual SOC designation and use the right value for that SOC. Update immap_85xx.h to include the GUTS PORDEVSR2 register. Signed-off-by: Timur Tabi <timur@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | dcache_enable() was missing for 440 and the patch 017e9b7925f74878d0e9475388cca9bda5ef9482 ["allow ports to override bootelf "] behavior uses this function.

| | | | | | | | | | | Currently U-Boot crashes on sequoia board in CPU POST if cache is enabled (CONFIG_4xx_DCACHE defined). The cache won't be disabled by change_tlb before CPU POST because there is an insufficient adress range check since CFG_MEM_TOP_HIDE was introduced. This patch tries to fix this problem.

* Use jr as register jump instructionShinya Kuribayashi2008-04-18-6/+6
| | | | | | | | | | Current assembler codes are inconsistent in the way of register jump instruction usage; some use jr, some use j. Of course GNU as allows both usages, but as can be expected from `Jump Register' the mnemonic `jr' is more intuitive than `j'. For example, Linux doesn't have `j <reg>' usage at all.
