* 85xx if NUM_CPUS>1, print cpu numberEd Swarthout2008-10-18-0/+5

* Have u-boot pass stashing parameters into device treeAndy Fleming2008-10-18-0/+11
| | | | | | | | | Some cores don't support ethernet stashing at all, and some instances have errata. Adds 3 properties to gianfar nodes which support stashing. For now, just add this support to 85xx SoCs. Signed-off-by: Andy Fleming <afleming@freescale.com>
* 85xx: Export invalidate_{i,d}cache and add flush_dcacheKumar Gala2008-10-18-0/+49
| | | | | | | | Added the ability for C code to invalidate the i/d-cache's and to flush the d-cache. This allows us to more efficient change mappings from cache-able to cache-inhibited. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* 85xx: Using proper I2C source clock divider for MPC8544Wolfgang Grandegger2008-10-08-2/+2
| | | | | | | | | Measurements with our MPC8544 board showed that the I2C bus frequency is wrong by a factor of 1.5. Obviously, the interpretation of the MPC85xx_PORDEVSR2_SEC_CFG bit of the cfg_sec_freq register is not correct. There seems to be an error in the 8544 RM.

* Fix the incorrect DDR clk freq reporting on 8536DSJason Jin2008-10-07-2/+4
| | | | | | | | | On 8536DS board, When the DDR clk is set async mode(SW3[6:8] != 111), The display is still sync mode DDR freq. This patch try to fix this. The display DDR freq is now the actual freq in both sync and async mode. Signed-off-by: Jason Jin <Jason.jin@freescale.com>
* 85xx: Remove setting of *cache-line-size in device treesKumar Gala2008-10-07-3/+0
| | | | | | | ePAPR says if the *cache-block-size is the same as *cache-line-size than we don't need the *cache-line-size property. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Fix printf errors under -DDEBUGAndrew Klossner2008-09-09-7/+7
| | | | | | | | | | | | Fix printf format-string/arg mismatches under -DDEBUG. These warnings occur with DEBUG defined for a platform using cpu/mpc85xx. Users of other architectures can unearth similar problems by adding the line "CFLAGS += -DDEBUG=1" in config.mk right after "CFLAGS += $(call cc-option,-fno-stack-protector)".

* 85xx: Ensure timebase is zero on secondary coresKumar Gala2008-09-09-0/+5
| | | | | | | The e500um says the timebase is volatile out of reset. To ensure TB sync works we need to make sure its zero. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* Pass in tsec_info struct through tsec_initializeAndy Fleming2008-09-02-23/+10
| | | | | | | | | | | | | The tsec driver contains a hard-coded array of configuration information for the tsec ethernet controllers. We create a default function that works for most tsecs, and allow that to be overridden by board code. It creates an array of tsec_info structures, which are then parsed by the corresponding driver instance to determine configuration. Also, add regs, miiregs, and devname fields to the tsec_info structure, so that we don't need the kludgy "index" parameter.

| | | | | | | | | | For some reason we duplicated the majority of code in lib_ppc/interrupts.c not show how that happened, but there is no good reason for it. Use the interrupt_init_cpu() and timer_interrupt_cpu() since its why they exist. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* FSL DDR: Rewrite the FSL mpc8xxx DDR controller setup code.Kumar Gala2008-08-27-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The main purpose of this rewrite it to be able to share the same initialization code on all FSL PowerPC products that have DDR controllers. (83xx, 85xx, 86xx). The code is broken up into the following steps: GET_SPD COMPUTE_DIMM_PARMS COMPUTE_COMMON_PARMS GATHER_OPTS ASSIGN_ADDRESSES COMPUTE_REGS PROGRAM_REGS This allows us to share more code an easily allow for board specific code overrides. Additionally this code base adds support for >4G of DDR and provides a foundation for supporting interleaving on processors with more than one controller.

| | | | | | | | | | | | | | | | | | | | The L2 size detection code was a bit confusing and we kept having to add code to it to handle new processors. Change the sense of detection so we look for the older processors that aren't changing. Also added support for 1M cache size on 8572. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
| * 8xxx-fdt: set ns16550 clock from CFG_NS16550_CLK, not bi_busfreqPaul Gortmaker2008-07-14-1/+1
| | | | | | | | | | | | | | | | | | | | Some boards that have external 16550 UARTs don't have a direct tie between bi_busfreq and the clock used for the UARTs. Boards that do have such a tie should set CFG_NS16550_CLK to be get_bus_freq(0) -- which most of them do already.

| | | | | | | | | | | | | | | | | | | | With a page size of BOOKE_PAGESZ_16M, both the real and effective addresses must be multiples of 16MB. The hardware silently truncates them so the code happens to work. This patch clarifies the situation by establishing addresses that the hardware doesn't need to truncate.

* Fix printf errors.Andrew Klossner2008-07-09-4/+4
| | | | | | | | | | | | The compiler will help find mismatches between printf formats and arguments if you let it. This patch adds the necessary attributes to declarations in include/common.h, then begins to correct the resulting compiler warnings. Some of these were bugs, e.g., "$d" instead of "%d" and incorrect arguments. Others were just annoying, like int-long mismatches on a system where both are 32 bits. It's worth fixing the annoying errors to catch the real ones. Signed-off-by: Andrew Klossner <andrew@cesa.opbu.xerox.com>

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.

| | | | | | | | | | | | | 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>

However, on systems with a lot of RAM, only a subset of the RAM is guaranteed to be mapped in and accessible.

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.

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