| * ppc: Enable full relocation to RAMPeter Tyser2009-10-03-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | The following changes allow U-Boot to fully relocate from flash to RAM: - Remove linker scripts' .fixup sections from the .text section - Add -mrelocatable to PLATFORM_RELFLAGS for all boards - Define CONFIG_RELOC_FIXUP_WORKS for all boards Previously, U-Boot would partially relocate, but statically initialized pointers needed to be manually relocated.

* ppc4xx: Big cleanup of PPC4xx definesStefan Roese2009-09-11-30/+30
| | | | | | | | | | | | | | | | This patch cleans up multiple issues of the 4xx register (mostly DCR, SDR, CPR, etc) definitions: - Change lower case defines to upper case (plb4_acr -> PLB4_ACR) - Change the defines to better match the names from the user's manuals (e.g. cprpllc -> CPR0_PLLC) - Removal of some unused defines Please test this patch intensive on your PPC4xx platform. Even though I tried not to break anything and tested successfully on multiple 4xx AMCC platforms, testing on custom platforms is recommended. Signed-off-by: Stefan Roese <sr@denx.de>
* General help message cleanupWolfgang Denk2009-06-12-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>
* ppc4xx: Add Sequoia RAM-booting targetStefan Roese2009-06-12-3/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 <sr@denx.de>

* ppc4xx: Fixup chip-selects in dtb for NAND-booting SequoiaStefan Roese2009-04-16-2/+56
| | | | | | | | | | | | | | | | | | | | Currently the NOR & NAND support in Linux only works for the "standard" Sequoia, the version booting for NOR flash. The NAND-booting version has the chip-selects swapped. Here the chip-select mappings: "Standard" NOR-booting version: CS0 NOR CS3 NAND NAND-booting version: CS0 NAND CS3 NOR With this path the dtb gets fixed-up, so that the correct chip-select numbers are patched in the dtb enabling correct NOR & NAND support in Linux on the NAND-booting Sequoia version.

* ppc4xx: Sequoia: Fix TLB reassignment in NAND booting codeStefan Roese2009-03-26-1/+1
| | | | | | | | | | 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.

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This 2nd patch now removes all UIC mask bit definition. They should be generated from the vectors by using the UIC_MASK() macro from now on. This way only the vectors need to get defined for new PPC's. Also only the really used interrupt vectors are now defined. This makes definitions for new PPC versions easier and less error prone. Another part of this patch is that the 4xx emac driver got a little cleanup, since now the usage of the interrupts is clearer. Signed-off-by: Stefan Roese <sr@denx.de>

* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-1/+1
| | | | | | | | | | | | | | | | | | | This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code.

* Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk2008-01-12-2/+2
| | | | | | | | | | | | | | | | | | | With recent toolchain versions, some boards would not build because or errors like this one (here for ocotea board when building with ELDK 4.2 beta): ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab] For many boards, the .bss section is big enough that it wraps around at the end of the address space (0xFFFFFFFF), so the problem will not be visible unless you use a 64 bit tool chain for development. On some boards however, changes to the code size (due to different optimizations) we bail out with section overlaps like above. The fix is to add the NOLOAD attribute to the .bss and .sbss sections, telling the linker that .bss does not consume any space in the image. Signed-off-by: Wolfgang Denk <wd@denx.de>

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 I2C bootstrap values that can be setup via the "bootstrap" command, were setup incorrect regarding the generation of the internal sync PCI clock. The values for PLB clock == 133MHz were slighly incorrect and the values for PLB clock == 166MHz were totally incorrect. This could lead to a hangup upon booting while PCI configuration scan. This patch fixes this issue and configures valid PCI divisor values for the sync PCI clock, with respect to the provided external async PCI frequency. Here the values of the formula in the chapter 14.2 "PCI clocking" from the 440EPx users manual: AsyncPCICLK - 1MHz <= SyncPCIClk <= (2 * AsyncPCIClk) - 1MHz 33MHz async PCI frequency: PLB = 133: => 32 <= 44.3 <= 65 (div = 3) PLB = 166: => 32 <= 55.3 <= 65 (div = 3) 66MHz async PCI frequency: PLB = 133: => 65 <= 66.5 <= 132 (div = 2) PLB = 166: => 65 <= 83 <= 132 (div = 2) Signed-off-by: Stefan Roese <sr@denx.de>

We now added the possibility to configure this register in the board config file, so that the default value of 8 can be overridden. Here the details of this patch: o drivers_pci_auto.c: introduce CFG_PCI_CACHE_LINE_SIZE to allow board-specific settings. As an example the sequoia board requires 0. Idea from Stefan Roese <sr@denx.de>. o board/amcc/sequoia/init.S: add a TLB mapping at 0xE8000000 for the PCI IO-space.
