| * | stm32: use level interrupt instead of edgeVincent Palatin2012-05-305-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using low level trigger interrupt rather than falling edge is more robust since we avoid detecting glitches or missing interrupts. This is backward compatible with the AP software expecting falling edge. Signed-off-by: Vincent Palatin <vpalatin@chromium.org> BUG=chrome-os-partner:8869 TEST=On Daisy, check we can still enter text in U-Boot console and Chrome browser (and check interrupt count increase as expected).

| * | Add basic SPI support to linkRandall Spangler2012-05-308-0/+221
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds SPI transaction support, and a debug command to read a few values from the SPI EEPROM. Note that the SPI controller is normally *disabled* with all its I/Os high-Z, so this will not interfere with main processor or Servo on the SPI bus. The bus is only enabled during the SPIROM command itself. BUG=chrome-os-partner:7844 TEST=manual 1) Reboot system 2) on EC console, 'spirom'. Should print Man/Dev ID : 0xef 0x16 JEDEC ID : 0xef 0x40 0x17 Unique ID : 0xd1 0x61 0x44 0xb0 0x63 0x5d 0x40 0x32 Status reg 1: 0x00 Status reg 2: 0x00 Note that unique ID is, well, unique, so it won't match my value. But it should still be something not all 0xff's. 3) Power on the system. x86 should still boot normally, indicating that the EC isn't interfering with the SPI bus.

| * | stm32f: update flash write sizeDavid Hendricks2012-05-291-2/+2
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This CL updates the constant FLASH_WRITE_BYTES to 64 and modifies the decrement value in the flash_physical_write() loop. The constant value was changed so that it would agree with EC_FLASH_SIZE_MAX which is the size of the data payload. FLASH_WRITE_BYTES is provided as part of EC_CMD_FLASH_INFO, so programs which query size this way will can take advantage of 64-byte writes. The decrement value in the loop did not actually change in value, but instead uses the size of the half-word.

* | Improve the timeout when running on non-Google EC boards.Louis Yung-Chieh Lo2012-05-301-2/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The udelay() has big overhead so that repeating calling leads big errors (expect 1 sec of timeout, but actually 12 secs of timeout). So, the improvement is to double the udelay count when BUSY bit is set. Even better, if we can check the I/O port content before really running the EC command, it can save more time. BUG=chrome-os-partner:10003 TEST=tested on link, alex, zgb, lumpy, stumpy and mario. Only mario takes 1 second to timeout. Others stop when checking ports (takes around 0.01 second).
