* ppc4xx: Big cleanup of PPC4xx definesStefan Roese2009-09-11-2/+2
| | | | | | | | | | | | | | | | 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>
* Fix all linker scripts for older binutils versions (pre-2.16)Wolfgang Denk2009-08-21-18/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f62fb99941c6 fixed handling of all rodata sections by using a wildcard combined with calls to ld's builtin functions SORT_BY_ALIGNMENT() and SORT_BY_NAME(). Unfortunately these functions were only introduced with biunutils version 2.16, so the modification broke building with all tool chains using older binutils. This patch makes it work again. This is done by omitting the use of these functions for such old tool chains. This will result in slightly larger target binaries, as the rodata sections are no longer in optimal order alignment-wise which reauls in unused gaps, but the effect was found to be insignificant - especially compared to the fact that you cannot build U-Boot at all in the current state. As ld seems to have no support for conditionals we run the linker script through the C preprocessor which can be easily used to remove the unwanted function calls. Note that the C preprocessor must be run with the "-ansi" (or a "-std=") option to make sure all the system-specific predefined macros outside the reserved namespace are suppressed. Otherise, cpp might for example substitute "powerpc" to "1", thus corrupting for example "OUTPUT_ARCH(powerpc)" etc. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Mike Frysinger <vapier@gentoo.org>
* ppc4xx: Canyonlands-NAND-boot: Support 2 Crucial 512MByte SODIMM'sStefan Roese2009-07-30-14/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Canyonlands boards are equipped with different SODIMM's. This is no problem with the "normal" NOR booting Canyonlands U-Boot, since it automatically detects the SODIMM's via SPD data and correctly configures them. But the NAND booting version is different. Here we only have 4k of image size to completely setup the hardware, including DDR2 setup. So we need to use a fixed DDR2 setup here. This doesn't work for different SODIMM's right now. Currently only this Crucial SODIMM is support: CT6464AC667.8FB (dual ranked) Now some boards are shipped with this SODIMM: CT6464AC667.4FE (single ranked) This patch now supports both SODIMM's by configuring first for the dual ranked DIMM. A quick shows, if this module is really installed. If this test fails, the DDR2 controller is re-configured for the single ranked SODIMM. Tested with those SODIMM's: CT6464AC667.8FB (dual ranked) CT6464AC667.4FE (single ranked) Signed-off-by: Stefan Roese <sr@denx.de>

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

|/ | | | | | | | | | | | | | | | | | We load the secondary stage u-boot image from NAND to system memory by nand_load, but we did not flush d-cache to memory, nor invalidate i-cache before we jump to RAM. When the system has cache enabled and the TLB/page attribute of system memory is cacheable, it will cause issues. - 83xx family is using the d-cache lock, so all of d-cache access is cache-inhibited. so you can't see the issue. - 85xx family is using d-cache, i-cache enable, partial cache lock. you will see the issue.

* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-3/+3
| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | 460EX doesn't support a fixed bootstrap option to boot from 512 byte page NAND devices. The only bootstrap option for NAND booting is option F for 2k page devices. So to boot from a 512 bype page device, the I2C bootstrap EEPROM needs to be programmed accordingly. This patch adds basic NAND booting support for the AMCC Canyonlands aval board and also adds support to the "bootstrap" command, to enable NAND booting I2C setting.

* Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk2008-01-12-4/+4
| | | | | | | | | | | | | | | | | | | 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>
