2018-04-23nand: zynq: Cleanup initializationEzequiel Garcia
CONFIG_NAND_ZYNQ selects CONFIG_SYS_NAND_SELF_INIT, so the driver doesn't have to play any ifdef game. Also, we can mark zynq_nand_init() as static and get rid of the mach-specific nand.h header. This is really a revert of: "mtd: zynq: nand: Move board_nand_init() function to board.c" (sha1: 310995d9f91ae56082b49be06fe8c3d01424f8f6) Signed-off-by: Ezequiel Garcia <ezequiel@vanguardiasur.com.ar> Reviewed-by: Michal Simek <michal.simek@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2018-04-21ARM: rmobile: Update E2 SilkMarek Vasut
The E2 Silk port was broken since some time. This patch updates the E2 Silk port to use modern frameworks, DM, DT probing, SPL for the preloading and puts it on par with the M2 Porter board. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org> --- NOTE: The port is missing support for I2C1 for DA9063 reset, since the I2C driver needs to be converted to DM and DT probing. That's not an issue for this patch though, since the reset was broken on Silk since forever.

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>

2018-04-15imx: hab: Provide hab_auth_img_or_fail commandBryan O'Donoghue
This patch adds hab_auth_img_or_fail() a command line function that encapsulates a common usage of authenticate and failover, namely if authenticate image fails, then drop to BootROM USB recovery mode. For secure-boot systems, this type of locked down behavior is important to ensure no unsigned images can be run. It's possible to script this logic but, when done over and over again the environment starts get very complex and repetitive, reducing that script repetition down to a command line function makes sense.

2018-04-15ARM: mx6: ddr: Add write leveling correction codeMarek Vasut
When the DDR calibration is enabled, a situation may happen that it will fail on a few select boards out of a whole production lot. In particular, after the first write leveling stage, the MPWLDECTRLx registers will contain a value 0x1nn , for nn usually being 0x7f or slightly lower. What this means is that the HW write leveling detected that the DQS rising edge on one or more bundles arrives slightly _after_ CLK and therefore when the DDR DRAM samples CLK on the DQS rising edge, the CLK signal is already high (cfr. AN4467 rev2 Figure 7 on page 18). The HW write leveling then ends up adding almost an entire cycle (thus the 0x17f) to the DQS delay, which indeed aligns it, but also triggers subsequent calibration failure in DQS gating due to this massive offset. There are two observations here: - If the MPWLDECTRLx value is corrected from 0x17f to 0x0 , then the DQS gating passes, the entire calibration passes as well and the DRAM is perfectly stable even under massive load. - When using the NXP DRAM calibrator for iMX6/7, the value 0x17f or so in MPWLDECTRx register is not there, but it is replaced by 0x0 as one would expect. Someone from NXP finally explains why, quoting [1]: " Having said all that, the DDR Stress Test does something that we do not advertise to the users. The Stress Test iself looks at the values of the MPWLDECTRL0/1 fields before reporting results, and if it sees any filed with a value greater than 200/256 delay (reported as half-cycle = 0x1 and ABS_OFFSET > 0x48), the DDR Stress test will reset the Write Leveling delay for this lane to 0x000 and not report it in the log. The reason that the DDR Stress test does this is because a delay of more than 78% a clock cycle means that the DQS edge is arriving within the JEDEC tolerence of 25% of the clock edge. In most cases, DQS is arriving < 5% tCK of the SDCLK edge in the early case, and it does not make sense to delay the DQS strobe almost a full clock cycle and add extra latency to each Write burst just to make the two edges align exactly. In this case, we are guilty of making a decision for the customer without telling them we are doing it so that we don't have to provide the above explanation to every customer. They don't need to know it. " This patch adds the correction described above, that is if the MPWLDECTRx value is over 0x148, the value is corrected back to 0x0.

The procedure is as follows: 1) Load u-boot-tpl.bin to 0xe6300000 2) Write magic number 0x1337c0de to 0xe6300020 TPL checks for this particular magic and starts JTAG recovery if this number is present. This is not present by default. 3) Start U-Boot TPL from 0xe6300000 4) Wait for a message from TPL on UART indicating JTAG boot: "JTAG boot detected!" 5) Halt the system in JTAG debugger 6) Load U-Boot image (u-boot.img) to 0x4fffffc0 7) Write magic number 0xb33fc0de to 0xe6300024 TPL checks for this particular magic to verify that the U-Boot image was loaded into DRAM by the JTAG debugger. 8) Resume the system in JTAG debugger Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>

Add and enable TPL on M2 Porter. The TPL must fit into 16 kiB due to the Gen2 BootROM restriction. The TPL is running from MERAM and is capable of performing the initial initialization of PFC, Clock, GPIO, LBSC, DBSC and QSPI NOR. DBSC is responsible for bringing up the DDR DRAM access. The TPL is capable of loading the next stage, U-Boot, from either SPI NOR or UART as a fallback. If either does provide a valid U-Boot uImage, the system stops, which allows the operator to load U-Boot ie. via JTAG and start it manually.

The at24 driver allows to register I2C EEPROM chips using different vendor and devices, but the I2C subsystem does not take the vendor into account when matching using the I2C table since it only has device entries. But when matching using an OF table, both the vendor and device has to be taken into account so the driver defines only a set of compatible strings using the "atmel" vendor as a generic fallback for compatible I2C devices. So add this generic fallback to the device node compatible string to make the device to match the driver using the OF device ID table.
