* ppc: Enable full relocation to RAMPeter Tyser2009-10-03-2/+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.

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* boards: get mac address from env and move load_sernum_ethaddr() to board initMike Frysinger2009-03-20-0/+3
| | | | | | | | | | | | | | | | | | | The environment is the canonical storage location of the mac address, so we're killing off the global data location and moving everything to querying the env directly. Rather than have common ppc code call a board-specific function like load_sernum_ethaddr(), have each board call it in its own board-specific misc_init_r() function. The boards that get converted here are: - kup4k/kup4x - pcs440ep - tqm8xx Signed-off-by: Mike Frysinger <vapier@gentoo.org> CC: Ben Warren <biggerbadderben@gmail.com> CC: Stefan Roese <sr@denx.de>
* TQM8xxL: make some room in low memory for future needsWolfgang Denk2009-02-19-1/+0
| | | | | | | | | THe TQM8xxL use a ahnd-optimized linker script to efficiently use the small boot sectors in the flash. This patch makes some room in the first sector to prepare for a size increase of lib_generic/vsprintf.o by a future patch. Signed-off-by: Wolfgang Denk <wd@denx.de>

* lwmon, tqm8xx: Fix build errorsAnatolij Gustschin2008-12-06-2/+3
| | | | | | | | | | | | | | | | Commit 6b59e03e0237a40a2305ea385defdfd92000978b lcd: Let the board code show board-specific info introduced some bugs which prevent U-Boot building for lwmon board if CONFIG_LCD_INFO_BELOW_LOGO will be defined in the board configuration. Also "LCD enabled" building for TQM823L doesn't work since this commit. This patch fixes above-mentioned issues. Signed-off-by: Anatolij Gustschin <agust@denx.de>
* Align end of bss by 4 bytesSelvamuthukumar2008-11-18-0/+1
| | | | | | | | | | Most of the bss initialization loop increments 4 bytes at a time. And the loop end is checked for an 'equal' condition. Make the bss end address aligned by 4, so that the loop will end as expected. Signed-off-by: Selvamuthukumar <selva.muthukumar@e-coninfotech.com> Signed-off-by: Wolfgang Denk <wd@denx.de>
* lcd: Let the board code show board-specific infoHaavard Skinnemoen2008-10-27-0/+26
| | | | | | | | | | | | | The information displayed when CONFIG_LCD_INFO is set is inherently board-specific, so it should be done by the board code. The current code dealing with this only handles two cases, and is already a horrible mess of #ifdeffery. Yes, this duplicates some code, but it also allows boards to print more board-specific information; this used to be very difficult.

* 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>
