* Fix the local bus divider mappingDave Liu2010-01-25-1/+6
| | | | | | | | The real clock divider is 4 times of the bits LCRR[CLKDIV], according the latest RevF RM. Signed-off-by: Dave Liu <daveliu@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | This reverts commit bc20f9a9527afe8ae406a74f74765d4323f04922. The original code was correct. I clearly need glasses or a brown paper bag. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | Content of the RSR is put into gd early so we can output it together with the CPU info. The clearing of gd in board_init_f is redundant for this architecture as it is done in cpu_init_f so we remove it. Signed-off-by: Detlev Zundel <dzu@denx.de>

| | | | | | | | | | | As per coding guidlines, it is good to maintain proper ordering in the makefiles. This was missed during initial coding, corrected here. This was discovered during orion5x code review Thanks to Albert Aribaud for this. Signed-off-by: Prafulla Wadaskar <prafulla@marvell.com>
* s5pc1xx: update cache routinesMinkyu Kang2010-01-23-45/+122
| | | | | | | | | | Because of v7_flush_dcache_all is moved to omap3/cache.S and s5pc110 needs cache routines, update s5pc1xx cache routines. l2_cache_enable and l2_caceh_disable are moved from cache.c to cache.S and invalidate_dcache is modified for SoC specific.

| * ppc4xx: Allow setting a single SPD EEPROM address for DDR2 DIMMsFelix Radensky2010-01-21-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On platforms where SPD EEPROM and another EEPROM have adjacent I2C addresses SPD_EEPROM_ADDRESS should be defined as a single element array, otherwise DDR2 setup code would fail with the following error: ERROR: Unknown DIMM detected in slot 1 However, fixing SPD_EEPROM_ADDRESS would result in another error: ERROR: DIMM's DDR1 and DDR2 type can not be mixed. This happens because initdram() routine does not explicitly initialize dimm_populated array. This patch fixes the problem.

| * mpc83xx: spd_sdram.c: Disable memory controller before initializingStefan Roese2010-01-07-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The memory controller could already be enabled, when spd_sdram() is called. This could be the case for example, when the SDRAM is initialized by the JTAG debugger. The "sync" after the register access via the accessor function is still needed, because the macro uses the sync before the real write is done. So until not all accesses are converted to using accessor functions, this sync still needs to be made "manually" here.

| | | | | | | | | | | | | | | | Now that we track which TLB CAM entries are used we can allocate entries on the fly. Change the SPD DDR TLB setup code to assume we use at most 8 TLBs (or the number free, which ever is fewer). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | We need to track which TLB CAM entries are used to allow us to "dynamically" allocate entries later in the code.

* USB Consolidate descriptor definitionsTom Rix2009-12-20-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The header files usb.h and usbdescriptors.h have the same nameed structure definitions for usb_config_descriptor usb_interface_descriptor usb_endpoint_descriptor usb_device_descriptor usb_string_descriptor These are out right duplicates in usb.h usb_device_descriptor usb_string_descriptor This one has extra unused elements usb_endpoint_descriptor unsigned char bRefresh unsigned char bSynchAddress; These in usb.h have extra elements at the end of the usb 2.0 specified descriptor and are used. usb_config_descriptor usb_interface_descriptor The change is to consolidate the definition of the descriptors to usbdescriptors.h. The dublicates in usb.h are removed. The extra element structure will have their name shorted by removing the '_descriptor' suffix. So usb_config_descriptor -> usb_config usb_interface_descriptor -> usb_interface For these, the common descriptor elements are accessed now by an element 'desc'. As an example - if (iface->bInterfaceClass != USB_CLASS_HUB) + if (iface->desc.bInterfaceClass != USB_CLASS_HUB) This has been compile tested on MAKEALL arm, ppc and mips.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the PPC reference implementation the udelay() function is responsible for resetting the watchdog timer as frequently as needed. Most other architectures do not meet that requirement, so long-running operations might result in a watchdog reset.
