| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Gala2008-08-27-2/+2432
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | This patch fixes some minor issues introduced with the patch: ppc4xx: Optimize PLB4 Arbiter... from Prodyut Hazarika: - Rework memory-queue and PLB arbiter optimization code, that the local variable is not needed anymore. This removes one #ifdef. - Use consistant spacing in ppc4xx.h header (XXX + 0x01 instead of XXX+ 0x01). This was not introduced by Prodyut, just a copy-paste problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Hammerhead platform is built around a AVR32 32-bit microcontroller from Atmel. It offers versatile peripherals, such as ethernet, usb device, usb host etc. The board also incooperates a power supply and is a Power over Ethernet (PoE) Powered Device (PD). Additonally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which will cover even the most exceptional need of memory bandwidth. Together with the onboard video decoder the board is ready for video processing.

* | | Clean up usage of icache_disable/dcache_disableKumar Gala2008-08-19-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no point in disabling the icache on 7xx/74xx/86xx parts and not also flushing the icache. All callers of invalidate_l1_instruction_cache() call icache_disable() right after. Make it so icache_disable() calls invalidate_l1_instruction_cache() for us. Also, dcache_disable() already calls dcache_flush() so there is no point in the explicit calls of dcache_flush(). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
