* mpc8323erdb: Improve the system performanceMichael Barkowski2008-03-25-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following changes are based on kernel UCC ethernet performance: 1. Make the CSB bus pipeline depth as 4, and enable the repeat mode 2. Optimize transactions between QE and CSB. Added CFG_SPCR_OPT switch to enable this setting. The following changes are based on the App Note AN3369 and verified to improve memory latency using LMbench: 3. CS0_CONFIG[AP_n_EN] is changed from 1 to 0 4. CS0_CONFIG[ODT_WR_CONFIG] set to 1. Was a reserved setting previously. 5. TIMING_CFG_1[WRREC] is changed from 3clks to 2clks (based on Twr=15ns, and this was already the setting in DDR_MODE) 6. TIMING_CFG_1[PRETOACT] is changed from 3clks to 2clks. (based on Trp=15ns) 7. TIMING_CFG_1[ACTTOPRE] is changed from 9clks to 6clks. (based on Tras=40ns) 8. TIMING_CFG_1[ACTTORW] is changed from 3clks to 2clks. (based on Trcd=15ns) 9. TIMING_CFG_1[REFREC] changed from 21 clks to 11clks. (based on Trfc=75ns) 10. TIMING_CFG_2[FOUR_ACT] is changed from 10 clks to 7clks. (based on Tfaw=50ns) 11. TIMING_CFG_2[ADD_LAT] and DDR_MODE[AL] changed from 0 to 1 (based on CL=3 and WL=2).

| | | | | | | | | | | | | | | | Add setup_c0_status from Linux. For the moment we disable interrupts, set CU0, mark the kernel mode, and clear ERL and EXL.

| * [MIPS] Implement flush_cache()Shinya Kuribayashi2008-03-25-0/+22
| | | | | | | | | | | | | | | | | | We do Hit_Writeback_Inv_D and Hit_Invalidate_I. You might think that you don't need to do Hit_Invalidate_I, but flush_cache() needs it since this function is used not only in U-Boot specfic programs but also at loading target binaries.

| * [MIPS] Fix I-/D-cache initialization loopsShinya Kuribayashi2008-03-25-39/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently we do 1) Index_Store_Tag_I, 2) Fill and 3) Index_Store_Tag_I again per a loop for I-cache initialization. But according to 'See MIPS Run', we're encouraged to use three separate loops rather than combining them *for both I- and D-cache*. This patch tries to fix this. In accordance with fixing above, mips_init_[id]cache are separated from mips_cache_reset(), and rewrite cache loops are completely rewritten with useful macros.

| | | | | | | | | | | | | | | | | | | | This patch replaces the current function definitions with NESTED, LEAF and END macro. They specify some more additional information about the function; an alignment of symbol, type of symbol, stack frame usage, etc. These information explicitly tells the assembler and the debugger about the types of code we want to generate.

| * [MIPS] Request for the 'mips_cache_lock()' removalShinya Kuribayashi2008-03-25-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The initial intension of having mips_cache_lock() was to use the cache as memory for temporary stack use so that a C environment can be set up as early as possible. But now mips_cache_lock() follow lowlevel_init(). We've already have the real memory initilaized at this point, therefore we could/should use it. No reason to lock at all. Other problems: Cache locking is not consistent across MIPS implementaions. Some imple- mentations don't support locking at all. The style of locking varies - some support per line locking, others per way, etc. Some parts use bits in status registers instead of cache ops. Current mips_cache_lock() is not necessarily general-purpose. And this is worthy of special mention; once U-Boot/MIPS locks the lines, they are never get unlocked, so the code relies on whatever gets loaded after U-Boot to re-initialize the cache and clear the locks. We're sup- posed to have CFG_INIT_RAM_LOCK and unlock_ram_in_cache() implemented, but leave the situation as it is for a long time. For these reasons, I proposed the removal of mips_cache_lock() from the global start-up code. This patch adds CFG_INIT_RAM_LOCK_MIPS to make existing users aware that *things have changed*. If he wants the same behavior as before, he needs to have CFG_INIT_RAM_LOCK_MIPS in his config file. If we don't have any regression report through several releases, then we'll remove codes entirely.

* LWMON5: POST RTC fixYuri Tikhonov2008-03-20-1/+3
| | | | | | | | | | | | | | | | | Modify the RTC API to provide one a status for the time reported by the rtc_get() function: 0 - a reliable time is guaranteed, < 0 - a reliable time isn't guaranteed (power fault, clock issues, and so on). The RTC chip drivers are responsible for providing this info if the corresponding chip supports such functionality. If not - always report that the time is reliable. The POST RTC test was modified to detect the RTC faults utilizing this new rtc_get() feature. Signed-off-by: Yuri Tikhonov <yur@emcraft.com>
* ppc4xx: Add Canyonlands NAND booting supportStefan Roese2008-03-15-1/+7
| | | | | | | | | | | | | | | 460EX doesn't support a fixed bootstrap option to boot from 512 byte page NAND devices. The only bootstrap option for NAND booting is option F for 2k page devices. So to boot from a 512 bype page device, the I2C bootstrap EEPROM needs to be programmed accordingly. This patch adds basic NAND booting support for the AMCC Canyonlands aval board and also adds support to the "bootstrap" command, to enable NAND booting I2C setting. Tested with 512 byte page NAND device (32MByte) on Canyonlands. Signed-off-by: Stefan Roese <sr@denx.de>

* PPC4xx (Sequoia): Fix Ethernet "remote fault" problemsMike Nuss2008-03-04-3/+2
| | | | | | | | | | | | | | Every now and then a Sequoia board (or equivalent hardware) had problems connecting to a Gigabit capable network interface. There were differences in the PHY setup between Linux and U-Boot. This patch fixes the problem. Apparently "remote fault" is being set, which signals to some devices (on the other end of the cable) that a fault has occurred, while other devices ignore it. I believe the RF bit was causing the issue, but I removed T4 also, to match up with Linux. Signed-off-by: Mike Nuss <mike@terascala.com>

| * 85xx: Don't icbi when unlocking the cacheKumar Gala2008-02-27-5/+2
| | | | | | | | | | | | | | | | | | There is no reason to icbi when invalidating the temporary stack in the d-cache. Its impossible on e500 to have the i-cache contain any addresses in the temp stack and it can be problematic in generating transactions on the bus to non-valid addresses.

| * 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.
