Randall Spangler	8b3a242ff0	Watchdog is reloaded by HOOK_TICK, not its own task ... This reduces memory footprint. BUG=chrome-os-partner:15714 BRANCH=none TEST=system still boots; 'waitms 1500' prints watchdog error dump Change-Id: Ieb0248a34655514b03d919cc36c2b369691da716 Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/36937 Reviewed-by: Simon Glass <sjg@chromium.org>	2012-10-30 15:33:24 -07:00
Randall Spangler	a3d62a3700	Switch to variable-size stacks ... Increase stack size slightly for vboot hash task since the vboot SHA256 function allocates ~300 bytes of stack data. Reduce stack size for watchdog, power LED, and a few other tasks with simple call trees where we can be sure an error path isn't going to blow past the reduced stack. This frees up ~1KB of RAM on STM32. BUG=chrome-os-partner:13814 BRANCH=all TEST=boot system; shmem should show more unused RAM; taskinfo should show tasks still have unused stack Change-Id: I47d6b77564a0180d15d86667cc0566a8919b776e Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/32608 Reviewed-by: Vincent Palatin <vpalatin@chromium.org>	2012-09-09 11:00:34 -07:00
