2018-12-06armv8: sec_firmware: return job ring status as true in TFABOOTPankit Garg
Returns job ring status as true in TFABOOT, as one job ring is always reserved. Signed-off-by: Ruchika Gupta <ruchika.gupta@nxp.com> Signed-off-by: Pankit Garg <pankit.garg@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>

2018-05-09armv8: sec_firmware: Remove JR3 from device tree node in all casesRuchika Gupta
JR3 was getting removed from device tree only if random number generation was successful. However, if SEC firmware is present, JR3 should be removed from device tree node irrespective of the random seed generation as SEC firmware reserves it for it's use. Not removing it in case of random number generation failure causes the kernel to crash. Random number generation was being called twice. This is not required. If SEC firmware is running, SIP call can be made to the SEC firmware to get the random number. This call itself would return failure if function is not supported. Duplicate calling of random number generation function has been removed. Signed-off-by: Ruchika Gupta <ruchika.gupta@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-01-15armv8: secure firmware: fix incorrect unit address in node nameAndre Przywara
The DT spec demands a unit-address in a node name to match the "reg" property in that node. Newer dtc versions will throw warnings if this is not the case. Remove the unit address from the config node name when U-Boot deals with secure firmware FIT images. Signed-off-by: Andre Przywara <andre.przywara@arm.com>
2017-10-27armv8: sec_firmware: Add support for loadables in FITSumit Garg
Enable support for loadables in SEC firmware FIT image. Currently support is added for single loadable image. Brief description of implementation: Add two more address pointers (loadable_h, loadable_l) as arguments to sec_firmware_init() api. Create new api: sec_firmware_checks_copy_loadable() to check if loadables node is present in SEC firmware FIT image. If present, verify loadable image and copies it to secure DDR memory. Populate address pointers with secure DDR memory addresses where loadable is copied. Example use-case could be trusted OS (tee.bin) as loadables node in SEC firmware FIT image.

2017-08-26ARMv8/sec_firmware : Update chosen/kaslr-seed with random numberRuchika Gupta
kASLR support in kernel requires a random number to be passed via chosen/kaslr-seed propert. sec_firmware generates this random seed which can then be passed in the device tree node. sec_firmware reserves JR3 for it's own usage. Node for JR3 is removed from device-tree. Signed-off-by: Ruchika Gupta <ruchika.gupta@nxp.com>
2017-06-01armv8: layerscape: Make U-Boot EL2 safeYork Sun
When U-Boot boots from EL2, skip some lowlevel init code requiring EL3, including CCI-400/CCN-504, trust zone, GIC, etc. These initialization tasks are carried out before U-Boot runs. This applies to the RAM version image used for SPL boot if PPA is loaded first. Signed-off-by: York Sun <york.sun@nxp.com>
2017-04-24arm: psci: make psci usable on single core socsYuantian Tang
PSCI can be used on both multiple and single core socs. Current implementation only allows PSCI to work on multiple core socs. This patch removes this restriction so that PSCI can work on single core socs as well.

2016-12-15ARMv8: LS1043A: change macro CONFIG_ARMV8_PSCI definitionmacro.wave.z@gmail.com
NXP/Freescale uses macro CONFIG_ARMV8_PSCI to enable their private PSCI implementation in PPA firmware, but this macro naming too generic, so this patch replaces it with a specic one CONFIG_FSL_PPA_ARMV8_PSCI. And this macro CONFIG_ARMV8_PSCI will be used for a generic PSCI for ARMv8 which will be added in following patchs.

2016-07-19ARMv8: add the secure monitor firmware frameworkHou Zhiqiang
This framework is introduced for ARMv8 secure monitor mode firmware. The main functions of the framework are, on EL3, verify the firmware, load it to the secure memory and jump into it, and while it returned to U-Boot, do some necessary setups at the 'target exception level' that is determined by the respective secure firmware. So far, the framework support only FIT format image, and need to define the name of which config node should be used in 'configurations' and the name of property for the raw secure firmware image in that config. The FIT image should be stored in Byte accessing memory, such as NOR Flash, or else it should be copied to main memory to use this framework.
