* MIPS: TXx9: Fix possible overflow in clock calculationsAtsushi Nemoto2009-05-143-3/+3
| | | | | | | | | | | Addition of -fwrapv option in 2.6.29 discloses possible overflow with signed arithmetics. For example, result of "a * 6 / 12" (int a = 400000000) is 200000000 without -fwrapv but -157913941 with -fwrapv. Change some variable to unsigned to avoid such overflows.

* 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.
