* relocation: Do not relocate NULL pointers.Joakim Tjernlund2009-10-08-2/+4
| | | | | | | | | | NULL is an absolute value and should not be relocated. After this correction code like: void weak_fun(void) __attribute__((weak)); printf("weak_fun:%p\n", weak_fun); will still print null after relocation. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
* 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.

* mucmc52, uc101: delete ata@3a00 node, if no CF card is detectedHeiko Schocher2009-09-25-0/+20
| | | | | | | | | | | U-Boot can detect if an IDE device is present or not. If not, and this new config option is activated, U-Boot removes the ATA node from the DTS before booting Linux, so the Linux IDE driver does not probe the device and crash. This is needed for buggy hardware (uc101) where no pull down resistor is connected to the signal IDE5V_DD7. Signed-off-by: Heiko Schocher <hs@denx.de>
* Reset i2c slave devices during init on mpc5xxx cpusEric Millbrandt2009-09-06-0/+49
| | | | | | | | | | | Reset any i2c devices that may have been interrupted during a system reset. Normally this would be accomplished by clocking the line until SCL and SDA are released and then sending a start condtiion (From an Atmel datasheet). There is no direct access to the i2c pins so instead create start commands through the i2c interface. Send a start command then delay for the SDA Hold time, repeat this by disabling/enabling the bus a total of 9 times. Signed-off-by: Eric Millbrandt <emillbrandt@dekaresearch.com>
* Add support for USB on PSC3 for the mpc5200Eric Millbrandt2009-08-25-2/+10
| | | | | | | | | | | Support USB on PSC3 on the mpc5200. Before this patch, enabling USB support would reconfigure PSC4 and PSC5 to USB. The mpc5200 does not support USB enabled on both the standard USB port and PSC3. This patch masks the appropriate bits when enabling USB.

* Replace __attribute references with __attribute__Peter Tyser2009-04-28-4/+4
| | | | | | | | __attribute__ follows gcc's documented syntax and is generally more common than __attribute. This change is only asthetic and should not affect functionality. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* mpc5200: reduce delays in i2cJon Smirl2009-04-05-3/+3
| | | | | | | | The previous code waited 1000us before checking i2c status. Measurement shows i2c is usually ready in under 50us. Change the polling interval to 15us, loop 6,667 times to keep the polling timeout constant at 100ms.
* mpc5200: suppress printf until console initializedJon Smirl2009-03-25-10/+20
| | | | | | | | | On boards which have the environment in eeprom, i2c_init() is called before the console and RAM are initialized. Suppress printfs until the console is initialized. Signed-off-by: Jon Smirl <jonsmirl@gmail.com> Acked-by: Heiko Schocher <hs@denx.de>

* 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>

| | | | | | | | | | Total5200 and digsy MTC use I2C port 2 pins as a ATA chip select. To avoid adding board-specific ifdefs to cpu/mpc5xxx/ide.c new define CONFIG_SYS_ATA_CS_ON_I2C2 was introduced. It is used by Total5200 and will be used by digsy MTC and other boards with ATA CS on I2C pins. Signed-off-by: Grzegorz Bernacki <gjb@semihalf.com>

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!

* PPC: Use r2 instead of r29 as global data pointerWolfgang Denk2008-02-14-1/+1
| | | | | | | | | | | | R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc will refuse to use load/store multiple insns; instead, it issues a list of simple load/store instructions upon function entry and exit, resulting in bigger code size, which in turn makes the build for a few boards fail. Use r2 instead. Signed-off-by: Wolfgang Denk <wd@denx.de>

* 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>
