      hikey: Disable VBUS_DET interrupt for PMIC · c9e8774c
      Leo Yan authored 
      

After disconnect Jumper pin 1-2 in J15 header, the signal VBUS_DET is to
be pulled down to low level. This will assert the interrupt signal in
PMIC and trigger IRQ in GIC; the asserted signal from VBUS_DET is level
triggered and kernel reports the warning for unhooked interrupt handling;
and VBUS_DET stays with low level, this triggers IRQ storm in kernel.

This patch is to disable interrupt for VBUS_DET in PMIC, this can
dismiss the verbose log and IRQ storm after kernel booting.

      hikey: Remove unnecessary code · c0cde364
      Victor Chong authored 
      

PLATFORM_LINKER_FORMAT
and
PLATFORM_LINKER_ARCH
defines are removed from
plat/hisilicon/hikey/include/platform_def.h
since there are already defined in
include/plat/common/common_def.h
which is included by
plat/hisilicon/hikey/hikey_def.h
which is included by
plat/hisilicon/hikey/include/platform_def.h

The line
$(eval $(call FIP_ADD_IMG,SCP_BL2,--scp-fw))
is removed from
plat/hisilicon/hikey/platform.mk
to clear the warning below:

Makefile:544: warning: overriding commands for target `check_SCP_BL2'
plat/hisilicon/hikey/platform.mk:19: warning: ignoring old commands for target `check_SCP_BL2'

$(eval $(call FIP_ADD_IMG,SCP_BL2,--scp-fw))
already exists in
Makefile
and applies to plat hikey so is redundant in
plat/hisilicon/hikey/platform.mk
