* 83xx/85xx/86xx: LBC register cleanupBecky Bruce2010-07-16-1/+1
| | | | | | | | | | | | | | | | | | | | | Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play. I have done a successful ppc build all and tested a board or two from each processor family.

* mpc8308: support for Freescale MPC8308 cpuIlya Yanok2010-07-09-8/+15
| | | | | | | | | | This patch adds basic support for Freescale MPC8308 CPU. Serial ports, NOR flash and integrated Ethernet controllers are supported. PCI Express is also supported. eSDHC, NAND and USB may work but aren't tested (using ULPI PHY requires additional patch).

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

* mpc83xx: Use CONFIG_FSL_ESDHC to enable sdhc clkRini van Zetten2010-04-22-5/+5
| | | | | | | | | | | Enable eSDHC Clock based on generic CONFIG_FSL_ESDHC define instead of a platform define. This will enable all the 83xx platforms to use sdhc_clk based on CONFIG_FSL_ESDHC. It's the same patch as commit 6b9ea08c5010eab5ad1056bc9bf033afb672d9cc for the ppc/85xx. Signed-off-by: Rini <rini@arvoo.nl> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
* Move arch/ppc to arch/powerpcStefan Roese2010-04-21-0/+549
As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
