u-boot.git/drivers/misc, branch v2021.04-rc2 Unnamed repository; edit this file 'description' to name the repository. common: Drop asm/global_data.h from common header 2021-02-02T20:33:42+00:00 Simon Glass sjg@chromium.org 2020-10-31T03:38:53+00:00 401d1c4f5d2d29c4bc4beaec95402ca23eb63295 Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

cros_ec: Add vstore support 2021-01-30T21:25:41+00:00 Simon Glass sjg@chromium.org 2021-01-16T21:52:31+00:00 10f746591fba16a48f0e3d14641be09f01982807 The EC can store small amounts of data for the benefit of the verified boot process. Since the EC is seldom reset, this can allow the AP to store data that survives a reboot or a suspend/resume cycle. Add support for this. Signed-off-by: Simon Glass <sjg@chromium.org>
