* arm: stm32f4: fix a bug when a random sector gets erasedVadzim Dambrouski2015-11-10-0/+1
| | | | | | | | | | Old sector number is not being cleared from FLASH_CR register. For example when first erased sector was 001 and then you want to erase sector 010, sector 011 gets erased instead. This patch clears old sector number from FLASH_CR register before a new one is written. Signed-off-by: Vadzim Dambrouski <pftbest@gmail.com>
* stm32f429: pass the device unique ID in DTBAntonio Borneo2015-07-27-0/+10
| | | | | | | | | | | | | | | | Read device unique ID and set environment variable "serial#". Value would then be passed to kernel through DTB. To read ID from DTB, kernel is required to have commit: 3f599875e5202986b350618a617527ab441bf206 (ARM: 8355/1: arch: Show the serial number from devicetree in cpuinfo) This commit is already mainline since v4.1-rc1.
