2014-03-04Add support for the Atmel SAMG53Andrey Yurovsky
flash: at91sam4: add support for the SAMG53 family (this also covers the SAMG51). The SAMG5x parts have an EEFC (enhanced embedded flash controller) which seems to be identical to the EFC that the sam4 driver supports. Add a script for the Xplained Pro G53 board, this has the onboard CMSIS-DAP debugger and a SAMG53N19. Tested on this board and chip combination.

2013-10-31Clean up many C99 integer types format specifiersPaul Fertser
This eliminates most of the warnings reported when building for arm-none-eabi (newlib). Hsiangkai, there're many similar warnings left in your nds32 files, I didn't have the nerve to clean them all, probably you could pick it up.

2013-10-15sam4s flash: remove unused bootstrap routineAndrey Yurovsky
Remove the static const array containing ARM instructions for a bootstrap program. Despite what the comment says, the DAP can write to the Flash and in fact this program is not referenced anywhere in openocd so it's a bit confusing having it in there. There should be no functionality change from this.

2012-10-04Modified Sector Erase for AT91SAM4SOlivier Schonken
In FLASHD_ErasePages AT91C_EFC_FCMD_EPA is used to erase sectors. According to the datasheet FARG[15:2] defines the page from which the erase will start.This page must be modulo 4, 8, 16 or 32 according to the number of pages to erase. FARG[1:0] defines the number of pages to be erased. Previously (firstpage << 2) was used to conform to this, seems it should not be shifted... Changed it to (firstPage) | erasePages.

2012-04-26topic: Added support for the SAM4S variantsOlivier Schonken
Atmel introduced 6 new Cortex-M4 processors on 2011-10-26 SAM4S16C - 1024KB flash LQFP100/BGA100 SAM4S16B - 1024KB flash LQFP64/QFN64 SAM4S16A - 1024KB flash LQFP48/QFN48 SAM4S8C - 512KB flash LQFP100/BGA100 SAM4S8B - 512KB flash LQFP64/QFN64 SAM4S8A - 512KB flash LQFP48/QFN48 The SAM4S processors still suffer from the "6 waitstates needed to program device" errata. Other relevant changes are: 1. Address of flash memory starts at 0x400000. 2. EWP (Erase page and write page) only works for the first two 8KB "sectors" 3. Because of the EWP not working for all the sectors, normal page writes have to be used. The default_flash_blank_check is used to check if lockregions should be erased. 4. The EA (Erase All) command takes 7.3s to complete. (Previous timeout was 500 ms) 5. There are 128 lockable regions of 8KB each. Implemented default blank checking, and page erase for load_image scenarios. This is to compensate for the EWP flash commands only working on the first 2 8KB sectors.
