| * ppc4xx: Consolidate PPC4xx SDRAM/DDR/DDR2 defines, part2Stefan Roese2008-06-03-0/+1156
| | | | | | | | | | | | | | This patch now adds a new header file (asm-ppc/ppc4xx-sdram.h) for all ppc4xx related SDRAM/DDR/DDR2 controller defines. Signed-off-by: Stefan Roese <sr@denx.de>
| * ppc4xx: Enable Primordial Stack for 40x and Unify ECC HandlingGrant Erickson2008-06-03-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (Part 1 of 2): * Rolls up a suite of changes to enable correct primordial stack and global data handling when the data cache is used for such a purpose for PPC40x-variants (i.e. CFG_INIT_DCACHE_CS). * Related to the first, unifies DDR2 SDRAM and ECC initialization by eliminating redundant ECC initialization implementations and moving redundant SDRAM initialization out of board code into shared 4xx code. * Enables MCSR visibility on the 405EX(r). * Enables the use of the data cache for initial RAM on both AMCC's Kilauea and Makalu and removes a redundant CFG_POST_MEMORY flag from each board's CONFIG_POST value. - Removed, per Stefan Roese's request, defunct memory.c file for Makalu and rolled sdram_init from it into makalu.c. With respect to the 4xx DDR initialization and ECC unification, there is certainly more work that can and should be done (file renaming, etc.). However, that can be handled at a later date on a second or third pass. As it stands, this patch moves things forward in an incremental yet positive way for those platforms that utilize this code and the features associated with it.

* | FSL LAW: Add new interface to use the last free LAWKumar Gala2008-06-11-0/+1

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make it so we keep track of which LAWs have allocated and provide a function (set_next_law) which can allocate a LAW for us if one is free. In the future we will move to doing more "dynamic" LAW allocation since the majority of users dont really care about what LAW number they are at. Also, add CONFIG_MPC8540 or CONFIG_MPC8560 to those boards which needed them Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Andy Fleming <afleming@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | PPC: add accessor macros to clear and set bits in one shot This patch adds macros from linux/include/asm-powerpc/io.h to clear and set bits in one shot using the in_be32, out_be32, etc. accessor functions.

* | 85xx: expose cpu identificationKumar Gala2008-06-10-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | The current cpu identification code is used just to return the name of the processor at boot. There are some other locations that the name is useful (device tree setup). Expose the functionality to other bits of code. Also, drop the 'E' suffix and add it on by looking at the SVR version when we print this out. This is mainly to allow the most flexible use of the name. The device tree code tends to not care about the 'E' suffix. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Limit the rate of h/w watch-dog triggering on the LWMON5 board by the CONFIG_WD_MAX_RATE value. Note that an earlier version of this patch which used microseconds instead of ticks dis not work. The problem was that we used usec2ticks() to convert microseconds into ticks. usec2ticks() uses get_tbclk(), which in turn calls get_sys_info(). It turns out that this function does a lot of prolonged operations (like divisions) which take too much time so we do not trigger the watchdog in time, and it resets the system.

* | Update SVR numbers to expand supportAndy Fleming2008-03-26-12/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | FSL has taken to using SVR[16:23] as an SOC sub-version field. This is used to distinguish certain variants within an SOC family. To account for this, we add the SVR_SOC_VER() macro, and update the SVR_* constants to reflect the larger value. We also add SVR numbers for all of the current variants. Finally, to make things neater, rather than use an enormous switch statement to print out the CPU type, we create and array of SVR/name pairs (using a macro), and print out the CPU name that matches the SVR SOC version.
