* Rename SPI erase functions to include opcodeCarl-Daniel Hailfinger2007-12-171-19/+19
| | | | | | | | | | | | | | | To make it easier to add new SPI chips to flashchips.c, rename functions with multiple possible opcodes from linear numbering at the end (_1, _2) to include the opcode at the end (_60, _c7). That way, you only have to take a short look at the data sheet and choose the right function by appending the opcode listed in the data sheet. No functional changes.

* Add generic SPI flash erase and write supportCarl-Daniel Hailfinger2007-10-181-5/+123
| | | | | | | | | | | | | The first chip the code was tested and verified with is the Macronix MX25L4005, but other chips should work as well. Timeouts are still hardcoded to data sheet maxima, but the status register checking code is already there. Thanks to Harald Gutmann for the initial code on which this is loosely based.
