Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value

2010-10-26T19:05:30Z

CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.

ppc4xx: TLB init file cleanup

2010-04-19T13:29:03Z

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

Replace "#include " with "#include "

2010-04-13T07:13:04Z

The appropriate include/asm-$ARCH directory should already by symlinked to include/asm so using the whole "asm-$ARCH" path is unnecessary. This change should also allow us to move the include/asm-$ARCH directories into their appropriate lib/$ARCH/ directories. Signed-off-by: Peter Tyser

ppc4xx: Add Sequoia RAM-booting target

2009-06-12T18:39:47Z

This patch adds another build target for the AMCC Sequoia PPC440EPx eval board. This RAM-booting version is targeted for boards without NOR FLASH (NAND booting) which need a possibility to initially program their NAND FLASH. Using a JTAG debugger (e.g. BDI2000/3000) configured to setup the SDRAM, this debugger can load this RAM- booting image to the target address in SDRAM (in this case 0x1000000) and start it there. Then U-Boot's standard NAND commands can be used to program the NAND FLASH (e.g. "nand write ..."). Here the commands to load and start this image from the BDI2000: 440EPX>reset halt 440EPX>load 0x1000000 /tftpboot/sequoia/u-boot.bin 440EPX>go 0x1000000 Please note that this image automatically scans for an already initialized SDRAM TLB (detected by EPN=0). This TLB will not be cleared. This TLB doesn't need to be TLB #0, this RAM-booting version will detect it and preserve it. So booting via BDI2000 will work and booting with a complete different TLB init via U-Boot works as well. Signed-off-by: Stefan Roese

ppc4xx: Sequoia: Fix TLB reassignment in NAND booting code

2009-03-26T17:36:40Z

This patch fixes a bug in the Sequoia TLB init code to reconfigure the correct TLB (boot space) after running from RAM. This bug was introduced with patch 4d332dbeb08f5863d1ea69d91a00c5499d3a87ed [ppc4xx: Make Sequoia boot vxWorks] which changed the order of the TLB in the Sequoia init.S file.

ppc4xx: Make Sequoia boot vxWorks

2008-01-10T18:06:54Z

vxWorks expects in TLB 0 a entry for the Machine Check interrupt TLB 1 a entry for the RAM TLB 2 a entry for the EBC TLB 3 a entry for the boot flash After changing the baudrate to 9600 I had no problems to boot the vxWorks image as distributed by WindRiver (Revision 2.0/1 from June 18, 2007) Signed-off-by: Niklaus Giger

ppc4xx: Add CONFIG_4xx_DCACHE compile options to enable cached SDRAM

2007-10-31T20:21:47Z

This patch adds the CONFIG_4xx_DCACHE options to some SDRAM init files and to the Sequoia TLB init code. Now the cache can be enabled on 44x boards by defining CONFIG_4xx_DCACHE in the board config file. This option will disappear, when more boards use is successfully and no more known problems exist. This is tested successfully on Sequoia and Katmai. The only problem that needs to be fixed is, that USB is not working on Sequoia right now, since it will need some cache handling code too, similar to the 4xx EMAC driver. Signed-off-by: Stefan Roese
