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>
2018-04-15imx: mx7: snvs: Add an SNVS init routineBryan O'Donoghue
Working with HAB on the i.MX7 we've encountered a case where a board that successfully authenticates u-boot when booting Linux via OPTEE subsequently fails to properly bring up the RTC. The RTC registers live in the low-power block of the Secure Non-Volatile Storage (SNVS) block. The root cause of the error has been traced to the HAB handing off the SNVS-RTC in a state where HPCOMR::NPSWA_EN = 0 in other words where the Non-Privileged Software Access Enable bit is zero. In ordinary circumstances this is OK since we typically do not run in TZ mode, however when we boot via HAB and enablng TrustZone, it is required to set HPCOMR::NPSWA_EN = 1 in order for the upstream Linux driver to have sufficient permissions to manipulate the SNVS-LP block. On our reference board it is the difference between Linux doing this: root@imx7s-warp-mbl:~# dmesg | grep rtc snvs_rtc_enable read 0x00000000 from SNVS_LPLR @ 0x00000034 snvs_rtc_enable read 0x00000021 from SNVS_LPCR @ 0x00000038 snvs_rtc_enable read 0x00000000 from SNVS_HPLR @ 0x00000000 snvs_rtc_enable read 0x80002100 from SNVS_HPCOMR @ 0x00000004 snvs_rtc 30370000.snvs:snvs-rtc-lp: rtc core: registered 30370000.snvs:snvs-rtc-lp as rtc0 snvs_rtc 30370000.snvs:snvs-rtc-lp: setting system clock to2018-04-01 00:51:04 UTC (1522543864) and doing this: root@imx7s-warp-mbl:~# dmesg | grep rtc snvs_rtc_enable read 0x00000000 from SNVS_LPLR @ 0x00000034 snvs_rtc_enable read 0x00000020 from SNVS_LPCR @ 0x00000038 snvs_rtc_enable read 0x00000001 from SNVS_HPLR @ 0x00000000 snvs_rtc_enable read 0x00002020 from SNVS_HPCOMR @ 0x00000004 snvs_rtc 30370000.snvs:snvs-rtc-lp: failed to enable rtc -110 snvs_rtc: probe of 30370000.snvs:snvs-rtc-lp failed with error -110 hctosys: unable to open rtc device (rtc0) Note bit 1 of LPCR is not set in the second case and is set in the first case and that bit 31 of HPCOMR is set in the second case but not in the first. Setting NPSWA_EN in HPCOMR allows us to boot through enabling TrustZone and continue onto the kernel. The kernel then has the necessary permissions to set LPCR::SRTC_ENV (RTC enable in the LP command register) whereas in contrast - in the failing case the non-privileged kernel cannot do so. This patch adds a simple init_snvs() call which sets the permission-bit called from soc.c for the i.MX7. It may be possible, safe and desirable to perform this on other i.MX processors but for now this is only tested on i.MX7 as working. Signed-off-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org>

2018-02-04imx: mx7: run sec_init for CAAM RNGBryan O'Donoghue
This patch adds a sec_init call into arch_misc_init(). Doing so in conjunction with the patch "drivers/crypto/fsl: assign job-rings to non-TrustZone" enables use of the CAAM in Linux when OPTEE/TrustZone is active. u-boot will initialise the RNG and assign ownership of the job-ring registers to a non-TrustZone context. With recent changes by Lukas Auer to fully initialize the RNG in sec_init() this means that u-boot will hand-off the CAAM in a state that Linux then can use the CAAM without touching the reserved DECO registers. This change is safe both for the OPTEE/TrustZone boot path and the regular non-OPTEE/TrustZone boot path.

2017-08-15env: Convert CONFIG_ENV_IS_IN... to a choiceSimon Glass
At present we support multiple environment drivers but there is not way to select between them at run time. Also settings related to the position and size of the environment area are global (i.e. apply to all locations). Until these limitations are removed we cannot really support more than one environment location. Adjust the location to be a choice so that only one can be selected. By default the environment is 'nowhere', meaning that the environment exists only in memory and cannot be saved. Also expand the help for the 'nowhere' option and move it to the top since it is the default.

2017-07-25Convert CONFIG_ENV_IS_IN_MMC/NAND/UBI and NOWHERE to KconfigSimon Glass
This converts the following to Kconfig: CONFIG_ENV_IS_IN_MMC CONFIG_ENV_IS_IN_NAND CONFIG_ENV_IS_IN_UBI CONFIG_ENV_IS_NOWHERE In fact this already exists for sunxi as a 'choice' config. However not all the choices are available in Kconfig yet so we cannot use that. It would lead to more than one option being set. In addition, one purpose of this series is to allow the environment to be stored in more than one place. So the existing choice is converted to a normal config allowing each option to be set independently. There are not many opportunities for Kconfig updates to reduce the size of this patch. This was tested with ./tools/moveconfig.py -i CONFIG_ENV_IS_IN_MMC And then manual updates. This is because for CHAIN_OF_TRUST boards they can only have ENV_IS_NOWHERE set, so we enforce that via Kconfig logic now.
