* ppc: Enable full relocation to RAMPeter Tyser2009-10-03-1/+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.

* stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD2009-07-18-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far the console API uses the following naming convention: ======Extract====== typedef struct device_t; int device_register (device_t * dev); int devices_init (void); int device_deregister(char *devname); struct list_head* device_get_list(void); device_t* device_get_by_name(char* name); device_t* device_clone(device_t *dev); ======= which is too generic and confusing. Instead of using device_XX and device_t we change this into stdio_XX and stdio_dev This will also allow to add later a generic device mechanism in order to have support for multiple devices and driver instances.

* Replace __asm references with __asm__Peter Tyser2009-04-28-17/+17
| | | | | | | | __asm__ follows gcc's documented syntax and is generally more common than __asm. This change is only asthetic and should not affect functionality. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* 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>
* AmigaOneG3SE/enet: get mac address from environmentMike Frysinger2009-03-20-34/+8
| | | | | | | | | | Always use the MAC address that is stored in the environment first before falling back to the ROM. This also cuts out any comparison steps: if the mac in the env is sane, the ROM is never consulted.

* | The PIPE_INTERRUPT flag is used wrongRemy Bohmer2008-10-14-1/+1
|/ | | | | | | | | | | | | | At a lot of places in the code the PIPE_INTERRUPT flags and friends are used wrong. The wrong bits are compared to this flag resulting in wrong conditions. Also there are macros that should be used for PIPE_* flags. This patch tries to fix them all, however, I was not able to test the changes, because I do not have any of these boards. Review required!

* 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>
* Big white-space cleanup.Wolfgang Denk2008-05-21-649/+613

* Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk2008-01-12-1/+1
| | | | | | | | | | | | | | | | | | | 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>

* Add support for a saving build objects in a separate directory.Marian Balakowicz2006-09-01-12/+19
| | | | | | | | | | | | | | | | | | | | | Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.
