fsl: improve the PIXIS code and fix a few bugs

2010-04-07T05:21:27+00:00

Refactor and document the Freescale PIXIS code, used on most 85xx and 86xx
boards.  This makes the code easier to read and more flexible.

Delete pixis.h, because none of the exported functions were actually being
used by any other file.  Make all of the functions in pixis.c 'static'.
Remove "#include pixis.h" from every file that has it.

Remove some unnecessary #includes.

Make 'pixis_base' into a macro, so that we don't need to define it in every
function.

Add "while(1);" loops at the end of functions that reset the board, so that
execution doesn't continue while the reset is in progress.

Replace in_8/out_8 calls with clrbits_8, setbits_8, or clrsetbits_8, where
appropriate.

Replace ulong/uint with their spelled-out equivalents.  Remove unnecessary
typecasts, changing the types of some variables if necessary.

Add CONFIG_SYS_PIXIS_VCFGEN0_ENABLE and CONFIG_SYS_PIXIS_VBOOT_ENABLE to make
it easier for specific boards to support variations in the PIXIS registers
sets.  No current boards appears to need this feature.

Fix the definition of CONFIG_SYS_PIXIS_VBOOT_MASK for the MPC8610 HPCD.
Apparently, "pixis_reset altbank" has never worked on this board.

mpc5121: cpu/mpc512x/diu.c: fix warnings

diu.c:158: warning: 'return' with no value, in function returning non-void
diu.c:162: warning: format '%ld' expects type 'long int', but argument 6 has type 'int'

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.

mpc512x: Add display of reset status register

2010-01-24T14:29:29+00:00

Content of the RSR is put into gd early so we can output it together
with the CPU info.  The clearing of gd in board_init_f is redundant for
this architecture as it is done in cpu_init_f so we remove it.

mpc512x: Use in/out accessors for all registers

2010-01-21T22:00:45+00:00

This is not only a cosmetic change as it fixes the real bug of board
reset not working with the ELDK 4.2 toolchain.

5xxx, fdt: move fdt_fixup_memory() to cpu.c file

2009-12-08T21:13:02+00:00

u-boot updates, before starting Linux, the memory node in the
DTS. As this is a "standard" feature, move this functionality
to the cpu.c file for mpc5xxx and mpc512x processors.
