Subject: [PATCH] Update Cortex branch of kernel to support HALSize env
variable. Export C version of hdr.OSEntries.
Detail:
Makefile - Now exports a C version of hdr.OSEntries, for use by the new HAL USB drivers
s/GetAll, s/Kernel - The HALSize env variable is now used in place of hard-coded values for the HAL size
s/HAL - Reset_IRQ_Handler now switches to SVC mode before calling HAL_KbdScanInterrupt, to allow the HAL USB drivers to re-enable interrupts if they wish.
s/VMSAv6 - Deleted some obsolete definitions
Admin:
Tested on rev C2 BB, A2 BB-xM, C1 TouchBook
Needs latest BuildSys, Env, HdrSrc
Version 5.35, 4.79.2.98.2.37. Tagged as 'Kernel-5_35-4_79_2_98_2_37'
