* headers: remove sched.h from interrupt.hAlexey Dobriyan2009-10-112-0/+2
| | | | | | | | After m68k's task_thread_info() doesn't refer to current, it's possible to remove sched.h from interrupt.h and not break m68k! Many thanks to Heiko Carstens for allowing this. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

| * phram: cleanup error handling and associated messagesMike Frysinger2009-09-191-13/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The error handling in the phram driver is pretty bad -- in many places, errors are silently ignored or logged, but then still ignored in the return value. So convert all of the code to pass back the correct return value and log error messages properly (and using the new pr_fmt() helper). If everything does go smoothly, rather than exit silently, dump a helpful info message like pretty much every other MTD driver does.

The latter form is obviously much better for performance, so let's use it when possible.

* mtd: Bug in m25p80.c during whole-chip eraseSteven A. Falco2009-04-291-5/+7
| | | | | | | | | | | | | | There is a logic error in "whole chip erase" for the m25p80 family. If the whole device is successfully erased, erase_chip() will return 0, and the code will fall through to the "else" clause, and do sector-by-sector erase in addition to the whole-chip erase. This patch corrects that. Also, the MAX_READY_WAIT_COUNT is insufficient for an m25p16 connected to a 400 MHz powerpc. Increasing it allows me to successfully program the device on my board.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes broken terminology added in the "m25p80.c erase enhance" patch, which added a chip erase command but called it "block erase". There are already two block erase commands; blocks are 4KiB or 32KiB. There's also a sector erase (usually 64 KiB). Chip erase typically covers Megabytes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit d0e8c47c58575b9131e786edb488fd029eba443e ("m25p80.c extended jedec support") added support for extended ids but in the process managed to break detection of all flashes. The ext jedec id check was inserted into an if statement that lacked braces, and it did not add the required braces. As such, the detection routine always returns the first entry in the SPI flash list.
