relocation: Do not relocate NULL pointers.

2009-10-08T07:33:36Z

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

ppc: Enable full relocation to RAM

2009-10-03T08:15:45Z

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 detected

2009-09-24T23:22:13Z

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

Reset i2c slave devices during init on mpc5xxx cpus

2009-09-06T09:26:04Z

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

Add support for USB on PSC3 for the mpc5200

2009-08-25T10:57:55Z

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. Signed-off-by: Eric Millbrandt Acked-by: Grant Likely Acked-by: Remy Bohmer

Replace attribute references with attribute__

2009-04-27T23:01:39Z

__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

mpc5200: reduce delays in i2c

2009-04-04T23:34:08Z

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 initialized

2009-03-25T21:50:04Z

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 Acked-by: Heiko Schocher
