* | MIPS: Make local arrays with CL_SIZE static __initdataAtsushi Nemoto2009-11-131-2/+2
|/ | | | | | | | | | | | | Since commit 22242681cff52bfb7cba5d2a37b91802be7a4e4c ("MIPS: Extend COMMAND_LINE_SIZE"), CL_SIZE is 4096 and local array variables with this size will cause an build failure with default CONFIG_FRAME_WARN settings. Although current users of such array variables are all early bootstrap code and not likely to cause real stack overflow (thread_info corruption), it is preferable to to declare these arrays static with __initdata.

* MIPS: TXx9: Fix spi-baseclk valueAtsushi Nemoto2009-11-021-1/+1
| | | | | | | | | | TXx9 SPI bit rate is calculated by: fBR = fSPI / 2 / (n + 1) (fSPI is SPI master clock freq, i.e. imbusclk freq.) So use imbus_clk / 2 as a spi-baseclk. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

| | | | | | | | | | | | | | 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.
