stm32/boards: Optimise flash and RAM allocation for L4 boards. 2019-07-01T06:57:20+00:00 Chris Mason 2019-05-12T14:13:59+00:00 378659209778a1bde24e9b15793087023b02bbd9 Optimisations are: - Remove FLASH_ISR section since devices with a small flash sector erase size don't need special FLASH_ISR handling. This reduces flash image by approx 1.5k. - Make SRAM2 contiguous with SRAM1 where possible. - Simplify configuration of 2k RAM buffer used for flash filesystem. RAM changes with this commit: - L432: stack 6k -> 10k, bss + heap 42k -> 52k - L476: stack 16k -> 30k, bss + heap 80k -> 96k - L496: stack 206k -> 16k, bss + heap 112k -> 302k

stm32/boards: Rework all stm32??xx_hal_conf.h files to use common code. 2019-06-25T04:18:24+00:00 Damien George 2019-06-25T03:42:06+00:00 009b1f6559fa2a621dcd35916886385327e6abc1 This eliminates a lot of duplicated code in these header files.

stm32/Makefile: Allow a board to config either 1 or 2 firmware sections. 2018-03-27T10:24:15+00:00 Damien George 2018-03-27T10:24:15+00:00 ed75b2655fd8e5f9c058a97852eb30f354c10206 This patch forces a board to explicitly define TEXT1_ADDR in order to split the firmware into two separate pieces. Otherwise the default is now to produce only a single continuous firmware image with all ISR, text and data together.

stm32/boards: Allow boards to have finer control over the linker script. 2018-03-27T10:17:48+00:00 Damien George 2018-03-27T10:17:48+00:00 7aec06ca9abb8e07ffce09b5a755e2a6f61b6749 This patch allows a particular board to independently specify the linker scripts for 1) the MCU memory layout; 2) how the different firmware sections are arranged in memory. Right now all boards follow the same layout with two separate firmware section, one for the ISR and one for the text and data. This leaves room for storage (filesystem data) to live between the firmware sections. The idea with this patch is to accommodate boards that don't have internal flash storage and only need to have one continuous firmware section. Thus the common.ld script is renamed to common_ifs.ld to make explicit that it is used for cases where the board has internal flash storage.

mpconfigboard_common.h now sets the defaults so there is no longer a need
to explicitly list all configuration options in a board's mpconfigboard.h
file.
