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.

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

BL2 is used to load BL31 and SCP_BL2. In HiKey platform, SCP_BL2
is the mcu firmware that is used to scale cpu frequency and switch
low power mode.

Initialize regulators, pins and eMMC in BL1. Only SRAM could be used in BL1.
So BL2 will be loaded from eMMC into SRAM later.
