* ppc 85xx: Fix whitespacesSascha Hauer2012-05-241-3/+3

* Minimal P2020RDB platform support and configuration fileRenaud Barbier2012-05-178-0/+593
| | | | | | | | | | | | | This is limited board support for the Freescale P2020RDB in single CPU mode. The DDR is configured for a memory bus running at 667Mhz. The system boots from NOR flash and provides the console at 115200 bauds, no other drivers are included. Finally, the PPC Kconfig and make file make the building of the P2020RDB platform firmware possible.

* Set _text_base to the firmware relocation addressRenaud Barbier2012-05-171-0/+4
| | | | | | | | | | _text_base assignment has been removed earlier from lib/board.c for the mpc5xxx. For the 85xx, _text_base is set to where the firmware relocates in memory as passed by the function input variable.

* MPC85xx start-up support codeRenaud Barbier2012-05-175-0/+334
| | | | | | | | | | This patch adds initialization functions used by the e500v2 start-up code and board specific code (L2 cache initialization). Other functions help identify the CPU or return the programmed memory size. Finally, the Makefile and Kconfig file are added.

* Initial e500v2 start up codeRenaud Barbier2012-05-173-0/+1089
| | | | | | | | | | | This is the first part of the start-up code. The source code origin is U-boot and is slightly modified to have e500v2 CPU support in 32-bit mode only. It includes the power-up entry point, CPU initialization code and exports definition for D-cache flush and I-cache invalidate.

* Preparation stage to support multiple PPC architecturesRenaud Barbier2012-05-0214-265/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | arch/ppc/Kconfig is reworked to make the configuration environment architecture neutral. All MPC5200 configuration is moved to the MPC5200 architecture specific configuration file. These modifications are reflected in the PCM030 board support. arch/ppc/Makefile compilation directives are updated in preparation for the introduction of future cpus/machines. lib/time.c is moved to the architecture specific directory and the building instructions updated in the Make files. The file is cleaned up of unused code. The definition of L1_CACHE_... is updated and CACHELINE_SIZE is defined in ppc/include/asm/cache.h for future use by the mpc85xx. The file mach-mpc5xxx/pci_mpc5200.c and mach-mpc5xxx/start.S are updated accordingly. The declaration of search_exception_table is moved in include/asm/common.h because it is used across architectures. mach-mpc5xxx/traps.c is also updated to reflect this change. The definition of exception in asm/ppc_asm.tmpl is updated for future use by the mpc85xx. The file starts.S in mach-mpc5xxx is updated accordingly.

| * bootm: use new uimage codeSascha Hauer2011-12-151-9/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This switches the bootm code to the new uimage code. Also bootm can now handle other types of images than uImages. Currently the only architecture making use of this is arm which allows to boot zImages, raw images and barebox images. I intended to make a more bisectable series from this but I failed becuase there are many dependencies and no matter how I tried the patches grew bigger and and bigger. So I decided to put this all in a single patch. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * Only pass -P to cpp when generating ld scriptsLoïc Minier2011-10-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building sandbox with ccache, one would hit warnings such as: warning: 'struct mmsghdr' declared inside parameter list on random files; a way to reproduce this issue is to build a simple file doing just: #include <sys/socket.h> int main(void) { return 0; } gcc -Wall -P -c -o foo foo.c But actually the -P flag is only useful when generating non-C files, such as linker scripts in the case of barebox. Removing the -P flag from all the gcc invocations, except when generating .lds files makes the warning go away. It turns out that this is what linux/scripts/Makefile.build also does nowadays.
