Randall Spangler	177dc398d3	Allow bigger flash write commands ... Version 1 of EC_CMD_FLASH_WRITE will use as big a write as possible given the available command parameter space. Falls back to 64 byte writes on old platforms. BUG=chrome-os-partner:20571 BRANCH=none TEST=Copy burn_my_ec onto a link and run it. Write size should be 64 bytes for the first half of the update (since the old EC doesn't support ver.1 of the write command) and 240 bytes for the second half of the update.

Randall Spangler	2730daa567	Comm interface now provides max I/O sizes and preallocated buffers ... The maximum packet / param size differs depending on interface and protocol version. Commands can now ask the comm interface what the limits are, and can use preallocated buffers to avoid needless malloc/free.

Randall Spangler	267dbb74d2	Add common interface to EC flash commands ... ectool and burn_my_ec need to use the same lower-level interface to the EC flash commands, rather than duplicating calling the low-level flash read/write/erase commands. This is a precursor to refactoring the low-level commands to support SPI/STM32L in a follow-up CL. BUG=chrome-os-partner:20571 BRANCH=none TEST=in a root shell, burn_my_ec flashes both RO and RW EC code Change-Id: I4c72690100d86dbff03b7dacc2fb248b571d3820 Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/60266	2013-07-01 16:14:15 -07:00
