* asm-generic: Consolidate errno.h to asm-generic/errno.hMichal Simek2009-07-09-1/+1
| | | | | | | | | | | | | | | This patch use blackfin errno.h implementation which correspond Linux kernel one. MIPS implemetation is different that's why I keep it. I removed ppc_error_no.h from Marvell boards which was the same too. I have got ack from ppc40x, blackfin, arm, coldfire and avr custodians.

* General help message cleanupWolfgang Denk2009-06-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Redundant Environment: protect full sector sizeWolfgang Denk2009-06-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several boards used different ways to specify the size of the protected area when enabling flash write protection for the sectors holding the environment variables: some used CONFIG_ENV_SIZE and CONFIG_ENV_SIZE_REDUND, some used CONFIG_ENV_SECT_SIZE, and some even a mix of both for the "normal" and the "redundant" areas. Normally, this makes no difference at all. However, things are different when you have to deal with boards that can come with different types of flash chips, which may have different sector sizes. Here we may have to chose CONFIG_ENV_SECT_SIZE such that it fits the biggest sector size, which may include several sectors on boards using the smaller sector flash types. In such a case, using CONFIG_ENV_SIZE or CONFIG_ENV_SIZE_REDUND to enable the protection may lead to the case that only the first of these sectors get protected, while the following ones aren't. This is no real problem, but it can be confusing for the user - especially on boards that use CONFIG_ENV_SECT_SIZE to protect the "normal" areas, while using CONFIG_ENV_SIZE_REDUND for the "redundant" area. To avoid such inconsistencies, I changed all sucn boards that I found to consistently use CONFIG_ENV_SECT_SIZE for protection. This should not cause any functional changes to the code.

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-10/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | There is no point in disabling the icache on 7xx/74xx/86xx parts and not also flushing the icache. All callers of invalidate_l1_instruction_cache() call icache_disable() right after. Make it so icache_disable() calls invalidate_l1_instruction_cache() for us. Also, dcache_disable() already calls dcache_flush() so there is no point in the explicit calls of dcache_flush(). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| * Update MTD to that of Linux 2.6.22.1William Juul2008-08-12-75/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot changed in the Linux MTD code, since it was last ported from Linux to U-Boot. This patch takes U-Boot NAND support to the level of Linux 2.6.22.1 and will enable support for very large NAND devices (4KB pages) and ease the compatibility between U-Boot and Linux filesystems. This patch is tested on two custom boards with PPC and ARM processors running YAFFS in U-Boot and Linux using gcc-4.1.2 cross compilers. MAKEALL ppc/arm has some issues: * DOC/OneNand/nand_spl is not building (I have not tried porting these parts, and since I do not have any HW and I am not familiar with this code/HW I think its best left to someone else.) Except for the issues mentioned above, I have ported all drivers necessary to run MAKEALL ppc/arm without errors and warnings. Many drivers were trivial to port, but some were not so trivial.

| | | | | | | | | | | | | | | | | | This patch removes some ft_board_setup() functions from some 4xx boards.

* | ppc4xx: Rework 440GX UIC handlingStefan Roese2008-07-11-19/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks the 440GX interrupt handling so that the common 4xx code can be used. The 440GX is an exception to all other 4xx variants by having the cascading interrupt vectors not on UIC0 but on a special UIC named UICB0 (UIC Base 0). With this patch now, U-Boot references the 440GX UICB0 when UIC0 is selected. And the common 4xx interrupt handling is simpler without any 440GX special cases. Also some additional cleanup to cpu/ppc4xx/interrupt.c is done. 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. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>

* 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>
