* MIPS: TXx9: Make firmware parameter passing more robustGeert Uytterhoeven2008-10-271-4/+18
| | | | | | | | | | | | | | When booting Linux on a txx9 board with VxWorks boot loader, it crashes in prom_getenv(), as VxWorks doesn't pass firmware parameters in a0-a3 (in my case, the actual leftover values in these registers were 0x80002000, 0x80001fe0, 0x2000, and 0x20). Make the parsing of argc, argv, and envp a bit more robust by checking if argc is a number below CKSEG0, and argv/envp point to CKSEG0.

* [MIPS] TXx9: Reorganize PCI codeAtsushi Nemoto2008-07-151-0/+51
Split out PCIC dependent code and SoC dependent code from board dependent code. Now TX4927 PCIC code is independent from TX4927/TX4938 SoC code. Also fix some build problems on CONFIG_PCI=n. As a bonus, "FPCIB0 Backplane Support" is available for all TX39/TX49 boards and PCI66 support is available for all TX49 boards.
