* fsl-ddr: Add extra cycle to turnaround timesDave Liu2010-04-26-0/+2
| | | | | | | | Add an extra cycle turnaround time to read->write to ensure stability at high DDR frequencies. Signed-off-by: Dave Liu <daveliu@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | add the macro definition for Rtt_Nom termination value for DDR3 Signed-off-by: Dave Liu <daveliu@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* ppc/p4080: Add p4080 DEVDISR2 & SRDS_PLLCR0 definesKumar Gala2010-04-26-2/+28
| | | | | | | Added some needed fines and some misc additional defines used by p4080 initialization. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* ppc/p4080: Extend the GUTS memory mapDave Liu2010-04-26-2/+12
| | | | | | | Extend pin control and clock control to GUTS memory map Signed-off-by: Dave Liu <daveliu@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* ppc/p4080: Fix synchronous frequency calculationsSrikanth Srinivasan2010-04-26-21/+25
| | | | | | | | | | | | | | | | | When DDR is in synchronous mode, the existing code assigns sysclk frequency to DDR frequency. It should be synchronous with the platform frequency. CPU frequency is based on platform frequency in synchronous mode. Also fix: * Fixes the bit mask for DDR_SYNC (RCWSR5[184]) * Corrects the detection of synchronous mode.

| * ppc4xx: TLB init file cleanupStefan Roese2010-04-19-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds new macros, with frequently used combinations of the 4xx TLB access control and storage attibutes. Additionally the 4xx init.S files are updated to make use of these new macros. Resulting in easier to read TLB definitions. Additionally some init.S files are updated to use the mmu header for the TLB defines, instead of defining their own macros. Signed-off-by: Stefan Roese <sr@denx.de>

| * | microblaze: Consolidate cache codeMichal Simek2010-04-16-44/+28
| | | | | | | | | | | | | | | | | | | | | Merge cpu and lib cache code. Flush cache before disabling. Signed-off-by: Michal Simek <monstr@monstr.eu>
| * | microblaze: Flush cache before jumping to kernelMichal Simek2010-04-16-0/+8
| | | | | | | | | | | | | | | | | | | | | There is used max cache size on system which doesn't define cache size. Signed-off-by: Michal Simek <monstr@monstr.eu>
| * | microblaze: Support system with WB cacheMichal Simek2010-04-16-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | WB cache use different instruction that WT cache but the major code is that same. That means that wdc.flush on system with WT cache do the same thing as before. You need newer toolchain with wdc.flush support. Signed-off-by: Michal Simek <monstr@monstr.eu>
| * | microblaze: Change initialization sequenceMichal Simek2010-04-16-3/+12
| | | | | | | | | | | | | | | | | | | | | env_relocation should be called first. Added stdio_init too. Signed-off-by: Michal Simek <monstr@monstr.eu>
| * | microblaze: Change cache report messagesMichal Simek2010-04-16-2/+2
| | | | | | | | | | | | | | | | | | It is more accurate to show that caches are OFF instead of FAIL. Signed-off-by: Michal Simek <monstr@monstr.eu>
| * | microblaze: Fix interrupt handler codeMichal Simek2010-04-16-17/+11
| | | | | | | | | | | | | | | | | | | | | It is better to read ivr and react on it than do long parsing from two regs. Interrupt controller returs actual irq number. Signed-off-by: Michal Simek <monstr@monstr.eu>
| * | microblaze: Move FSL initialization to board.cMichal Simek2010-04-16-8/+6

| * | microblaze: Move timer initialization to board.cMichal Simek2010-04-16-7/+9
| | | | | | | | | | | | | | | | | | | | | I would like to handle case where system doesn't contain intc that's why I need timer initialization out of intc code. Signed-off-by: Michal Simek <monstr@monstr.eu>
| * | microblaze: Fix irq.S codeMichal Simek2010-04-16-120/+62
| | | | | | | | | | | | | | | | | | | | | It is ancient code. There is possible to save several instructions just if we use offset instead of addik Signed-off-by: Michal Simek <monstr@monstr.eu>
| * | microblaze: Add FDT supportArun Bhanu2010-04-16-5/+34
| |/ | | | | | | | | | | | | | | | | | | This patch adds FDT (flattened device tree) support to microblaze arch. Tested with Linux arch/microblaze kernels with and without compiled in FDT on Xilinx ML506 board. Signed-off-by: Arun Bhanu <arun@bhanu.net> Signed-off-by: Michal Simek <monstr@monstr.eu>
* | Move arch/ppc to arch/powerpcStefan Roese2010-04-21-60/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.

* ppc4xx: Add option for PPC440SPe ports without old Rev. A supportStefan Roese2010-04-14-1/+1
| | | | | | | | | | | The 440SPe Rev. A is quite old and newer 440SPe boards don't need support for this CPU revision. Since removing support for this older version simplifies the creation for newer U-Boot ports, this patch now enables 440SPe > Rev. A support by creating the CONFIG_440SPE_REVA define. By defining this in the board config header, Rev. A will still be supported. Otherwise (default for newer board ports), Rev. A will not be supported. Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | This helps to clean up the include/ directory so that it only contains non-architecture-specific headers and also matches Linux's directory layout which many U-Boot developers are already familiar with. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* Move lib_$ARCH directories to arch/$ARCH/libPeter Tyser2010-04-13-0/+18167
Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
