From ef7557b4fd1a6a889d9918b2811567af216ebaf3 Mon Sep 17 00:00:00 2001 From: David Hendricks Date: Tue, 29 May 2012 22:03:34 -0700 Subject: [PATCH] stm32f: update flash write size 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.
