* Fix calculation of I2C clock for some 86xx chipsTimur Tabi2008-04-30-1/+13
| | | | | | | | | Some 86xx chips use CCB as the base clock for the I2C, and others used CCB/2. 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.

* 85xx: Add -mno-spe to e500/85xx buildsKumar Gala2008-04-29-0/+1
| | | | | | | | | | | Newer gcc's might be configured to enable autovectorization by default. If we happen to build with one of those compilers we will get SPE instructions in random code. -mno-spe disables the compiler for automatically generating SPE instructions without our knowledge.

| | | | | | | | | | | | | | | | | | | | Since the current dflush() implementation is know to have some problems (as seem on lwmon5 ECC init) this patch removes it completely and replaces it by using clean_dcache_range(). Tested on Katmai with ECC DIMM. Signed-off-by: Stefan Roese <sr@denx.de>

|/ | | | | | | | | | | | | | | | | * 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.

| | | | | | | | | | | | | | | | | | | | 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.

| * | 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.

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

* 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.
