2017-06-14Unique names for defines in the CPU librariesVarun Wadekar
This patch makes all the defines in the CPU libraries unique, by prefixing them with the CPU name. NOTE: PLATFORMS USING THESE MACROS WILL HAVE TO UPDATE THEIR CODE TO START USING THE UPDATED NAMES Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>
2017-06-08rockchip: check wakeup cpu when resumeLin Huang
unlike rk3399 and rk3368, there are some rockchip 64bit SOC do not have CPUPD, and pmu_cpuson_entrypoint() is common function for rockchip platform, so we need to check wakeup cpu when resume. Change-Id: I6313e8a9d7c16b03e033414f0cb281646c2159ff Signed-off-by: Lin Huang <hl@rock-chips.com>

2017-01-24Use #ifdef for IMAGE_BL* instead of #ifMasahiro Yamada
One nasty part of ATF is some of boolean macros are always defined as 1 or 0, and the rest of them are only defined under certain conditions. For the former group, "#if FOO" or "#if !FOO" must be used because "#ifdef FOO" is always true. (Options passed by $(call add_define,) are the cases.) For the latter, "#ifdef FOO" or "#ifndef FOO" should be used because checking the value of an undefined macro is strange. Here, IMAGE_BL* is handled by make_helpers/build_macro.mk like follows: $(eval IMAGE := IMAGE_BL$(call uppercase,$(3))) $(OBJ): $(2) @echo " CC $$<" $$(Q)$$(CC) $$(TF_CFLAGS) $$(CFLAGS) -D$(IMAGE) -c $$< -o $$@ This means, IMAGE_BL* is defined when building the corresponding image, but *undefined* for the other images. So, IMAGE_BL* belongs to the latter group where we should use #ifdef or #ifndef. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

We have lots of duplicated defines (and comment blocks too). Move them to include/plat/common/common_def.h. While we are here, suffix the end address with _END instead of _LIMIT.

2016-10-25rockchip: clear the power mode status via M0Caesar Wang
Due to the PMU design, the PMU may not clear the WAKEUP bit after wakeup, therefore, the state machine at the power mode may enter the infinite loop during WFI. There is a solution that we can use the M0 to monitor the WAKEUP bit and clear it during power mode, then the state machine will be recovered immediately. Then, the DUT can exit the WFI normally.

Add the common extra.ld.S and customized rk3399.ld.S to extend to more features for different platforms. For example, we can add SRAM section and specific address to load there if we need it, and the common bl31.ld.S not need to be modified. Therefore, we can remove the unused codes which copying explicitly from the function pmusram_prepare(). It looks like more clear.

2016-09-08rockchip: fix the scu idle for rk3399Tony Xie
As rk3399 reported the d8/octane scores drop 10% with cpu idle. The root cause is thc cpu cluster enter the slow mode. We don't need switch the clock to 24MHz if cpu cluster enter the retention mode. In order to improve performance, it just needs for cluster enter powering off mode. Also, we shouldn't do anything for hlvl if the system is off. Change-Id: I2a02962a01343abd0cba47ed63192c1cdf88b119

2016-07-18rockchip: support plat SIP runtime serviceCaesar Wang
Software executing in the normal world and in the trusted world at exception levels lower than EL3 will request runtime services using the SMC instruction. See the documentation here: https://github.com/ARM-software/arm-trusted-firmware/blob/master/docs/ rt-svc-writers-guide.md This to be implemented as an EL3 Runtime Service in rockchip BL31 platform port, using the "SiP Service Call" range as specified in the SMC Calling Convention. This doesn't support any SMC yet, we will support it in later. Change-Id: I0a638dd0b653c28b08f79d89f77ed7c69864017d
2016-07-08Introduce utils.h header fileSandrine Bailleux
This patch introduces a new header file: include/lib/utils.h. Its purpose is to provide generic macros and helper functions that are independent of any BL image, architecture, platform and even not specific to Trusted Firmware. For now, it contains only 2 macros: ARRAY_SIZE() and IS_POWER_OF_TWO(). These were previously defined in bl_common.h and xlat_tables.c respectively. bl_common.h includes utils.h to retain compatibility for platforms that relied on bl_common.h for the ARRAY_SIZE() macro. Upstream platform ports that use this macro have been updated to include utils.h. Change-Id: I960450f54134f25d1710bfbdc4184f12c049a9a9

2016-05-27rockchip: add reset or power off gpio configuration for rk3399Caesar Wang
We add plat parameter structs to support BL2 to pass variable-length, variable-type parameters to BL31. The parameters are structured as a link list. During bl31 setup time, we travse the list to process each parameter. throuth this way, we can get the reset or power off gpio parameter, and do hardware control in BL31. This structure also can pass other parameter to BL31 in future.
2016-05-27rockchip: support rk3399 gpio driverCaesar Wang
There are 5 groups of GPIO (GPIO0~GPIO4), totally have 122 GPIOs on rk3399 platform. The pull direction(pullup or pulldown) for all of GPIOs are software-programmable. At the moment, we add the gpio basic driver since reset or power off the devices from gpio configuration for BL31.
