kgdb: cpu/mpc* cpu/74xx: include kgdb.h when needed

2010-02-08T21:05:42+00:00

Commit cbb0cab1d929839d broke some platforms which used kgdb code but
didn't actually include kgdb.h.  So include kgdb.h in all the relevant
traps code.

ppc: remove -ffixed-r14 gcc option.

2010-01-26T18:30:16+00:00

This is no loger needed, free up r14 for general usage.

ppc: Use r12 instead of r14 as GOT pointer.

2010-01-26T18:30:13+00:00

r14 is not supposed to be clobbered by functions. Switch
to r12 and call GET_GOT when needed. This will allow u-boot
to loose the -ffixed-r14 gcc option.

ppc: Loose GOT access in IRQ

2010-01-26T18:30:12+00:00

Using the GOT in IRQ handlers requires r14 to be -ffixed-r14.
Avoid this by relocatate transfer_to_handler too.
This will allow to free up r14 later on.

kgdb: drop duplicate debugger_exception_handler

2010-01-17T23:23:33+00:00

The debugger_exception_handler definition is the same for everyone, so use
the common one now.

relocation: Do not relocate NULL pointers.

2009-10-08T07:33:36+00:00

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.

ppc: Enable full relocation to RAM

2009-10-03T08:15:45+00:00

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.

i2c: Create common default i2c_[set|get]_bus_speed() functions

2009-06-12T18:39:45+00:00

New default, weak i2c_get_bus_speed() and i2c_set_bus_speed() functions
replace a number of architecture-specific implementations.

Also, providing default functions will allow all boards to enable
CONFIG_I2C_CMD_TREE.  This was previously not possible since the
tree-form of the i2c command provides the ability to display and modify
the i2c bus speed which requires i2c_[set|get]_bus_speed() to be
present.
