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>
2018-05-06arm: mach-omap2: cache: Explicitly enable I cacheLokesh Vutla
omap-common cache enabling sequence relies on cpu_init_cp15() (inside start.S) for enabling I-caches. But cpu_init_cp15() can be skipped if CONFIG_SKIP_LOWLEVEL_INIT is defined. So enable I-caches if not enabled already.

2018-04-28arm: move SYS_ARCH_TIMER to KConfigAndre Przywara
SYS_ARCH_TIMER guards the usage of the ARM Generic Timer (aka arch timer) in U-Boot. At the moment it is mandatory for ARMv8 and used by a few ARMv7 boards. Add a proper Kconfig symbol to express this dependency properly, allowing certain board configuration to later disable arch timer in case there are any problems with it.

2018-04-27clang: Update documentationTom Rini
As of clang-5.0, things have changed a bit. First, we cannot automatically guess -target values as if we do not pass one with CC then cc-option will fail. Second, to disable movt/movw relocations the argument has become -mno-movt. Related to the target part, we cannot use arm-none-eabi as that ends up being too generic of an ARM target for things like say rpi_3_32b to work. Signed-off-by: Tom Rini <trini@konsulko.com>

This converts the following to Kconfig: CONFIG_SPI This partly involves updating code that assumes that CONFIG_SPI implies things that are specific to the MPC8xx SPI driver. For now, just update the CONFIG tests. This also involves reworking the default for CONFIG_SYS_DEF_EEPROM_ADDR so that we don't set it when we cannot make a reasonable default, as it does not cause any compile failures.

2018-04-26arm,imx6: fix PAD_CTL_SPEED_LOW constantMark Jonas
For most i.MX6 processors the PAD_CTL_SPEED_LOW constant is the same. Only the i.MX6 SoloLite is an exemption. So far the code did not consider that.

2018-04-15imx: Create distinct pre-processed mkimage config filesTrent Piepho
Each imx image is created by a separate sub-make and during this process the mkimage config file is run though cpp. The cpp output is to the same file no matter what imx image is being created. This means if two imx images are generated in parallel they will attempt to independently produce the same pre-processed mkimage config file at the same time. Avoid the problem by making the pre-processed config file name unique based on the imx image it will be used in. This way each image will create a unique config file and they won't clobber each other when run in parallel. This should fixed the build bug referenced in b5b0e4e3 ("imximage: Remove failure when no IVT offset is found").

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>
