There is no HDMI on i.MX8MM, so we need to remove HDMI entry, then we could not reuse imximage.cfg, so create a new one. Signed-off-by: Peng Fan <peng.fan@nxp.com>
2019-10-08ddr: imx8m: fix ddr firmware location when enable SPL OFPeng Fan
With CONFIG_SPL_OF_CONTROL, the device tree will be padded to end of the u-boot-spl-nodtb.bin, however we also put the ddr firmware file to this location, so need to adapt the code with SPL OF and align to 4 bytes to ease copy firmware.

2019-10-08tools: imx8m_image: align spl bin image sizePeng Fan
The loader for the DDR firmware in drivers/ddr/imx/imx8m/helper.c uses a 4-byte-aligned address to load the firmware. In cases where OF is enabled in SPL the dtb will be appended to the SPL binary and can result in a binary that is not aligned correctly. If OF is not enabled in SPL, `_end` is already aligned correctly, but this patch does not hurt. To ensure the correct alignment we use dd to create a temporary file u-boot-spl-pad.bin with the correct padding.

2019-10-08imx: Kconfig: Reduce default CONFIG_CSF_SIZEBreno Matheus Lima
The default CSF_SIZE defined in Kconfig is too high and SPL cannot fit into the OCRAM in certain cases. The CSF cannot achieve 0x2000 length when using RSA 4K key which is the largest key size supported by HABv4. According to AN12056 "Encrypted Boot on HABv4 and CAAM Enabled Devices" it's recommended to pad CSF binary to 0x2000 and append DEK blob to deploy encrypted boot images. As the maximum DEK blob size is 0x58 we can reduce CSF_SIZE to 0x2060 which should cover both CSF and DEK blob length. Update default_image.c and image.c to align with this change and avoid a U-Boot proper authentication failure in HAB closed devices: Authenticate image from DDR location 0x877fffc0... bad magic magic=0x32 length=0x6131 version=0x38 bad length magic=0x32 length=0x6131 version=0x38 bad version magic=0x32 length=0x6131 version=0x38 spl: ERROR: image authentication fail Fixes: 96d27fb218 (Revert "habv4: tools: Avoid hardcoded CSF size for SPL targets") Reported-by: Jagan Teki <jagan@amarulasolutions.com> Signed-off-by: Breno Lima <breno.lima@nxp.com>

2019-10-08spi: Add support for SPL_OF_PLATDATA to mxs_gpio.c driverLukasz Majewski
After this patch the mxs_gpio.c DM/DTS driver can be used at early SPL to read states of gpio pins (and for example alter the boot flow). It was necessary to adjust its name to 'fsl_imx_2{38}_gpio' to match requirements for SPL_OF_PLATDATA usage. Signed-off-by: Lukasz Majewski <lukma@denx.de>
2019-10-08mmc: Replace printf with debug call for timeouts in the i.MX28 mxs driverLukasz Majewski
This change replaces printf() with debug() for the notification about commands timeouts. This is done on purpose (also other drivers use such approach - dw_mmc.c, mvebu_mmc.c), as the mmc core code (mmc.c) uses timeouts to assess if one is using sd card or eMMC device. In such situation timeout is a some kind of a "normal" behavior and there shall not be any output to the console. There is no impact on boot time for boards using this driver (even in SPL) when two extra timeouts are returned (no SD card present, only eMMC available). Boot time tested with grabserial: sudo grabserial -b 115200 -d /dev/ttyUSB1 -e 30 -t -m "^U-Boot SPL*" Signed-off-by: Lukasz Majewski <lukma@denx.de>
2019-10-08mmc: Convert mxsmmc eMMC driver for i.MX2{38} to DM/DTSLukasz Majewski

2019-10-08spi: Add support for SPL_OF_PLATDATA to mxs_spi.c driverLukasz Majewski
After this patch the mxs_spi.c DM/DTS driver can be used at early SPL to read payload from SPI-NOR memories. It was necessary to adjust its name to 'fsl_imx_2{38}_spi' to match requirements for SPL_OF_PLATDATA usage. Signed-off-by: Lukasz Majewski <lukma@denx.de>
2019-10-08spi: fix: Call mxs_reset_block() during DM/DTS probeLukasz Majewski
Without this change the DM/DTS version of mxs_spi driver doesn't reset the SPI IP block in probe. As a result this driver (when used solely on U-Boot proper) relies on reset performed by mxs spi driver in SPL. In the use case where eMMC is used in SPL as a boot primary device, the mxs_reset_block() is not called at all and DM/DTS aware SPI driver in U-Boot proper is malfunctioning.

2019-10-08spl: Init proper struct driver member (platdata_auto_alloc_size) for mxs_spiLukasz Majewski

2019-10-08dts: imx28: Remove #include "imx28.dtsi" from imx28-u-boot.dtsi fileLukasz Majewski
After this change it is possible to use imx28-<board>-u-boot.dtsi with the imx28-u-boot.dtsi explicitly included without breaking setup from imx28-<board>.dts file. The problem is that the imx28.dtsi included in a wrong place overrides the changes made in imx28-<board>.dts. As a result some devices are "disabled" in the final DTB. Signed-off-by: Lukasz Majewski <lukma@denx.de>
2019-10-08imx: Introduce CONFIG_SPL_FORCE_MMC_BOOT to force MMC boot on falcon modeLukasz Majewski
This change tries to fix the following problem: - The board boots (to be more precise - ROM loads SPL) from a slow SPI-NOR memory. As a result the spl_boot_device() will return SPI-NOR as a boot device (which is correct). - The problem is that in 'falcon boot' the eMMC is used as a boot medium to load kernel from its partition. Calling spl_boot_device() will break things as it returns SPI-NOR device. To fix this issue the new CONFIG_SPL_FORCE_MMC_BOOT Kconfig flag is introduced to handle this special use case. By default it is not defined, so there is no change in the legacy code flow. Signed-off-by: Lukasz Majewski <lukma@denx.de>
2019-10-08imx: Rewrite display5 get_board_id() function to use dm_gpio_* APILukasz Majewski
The get_board_id() function was using the old gpio_* compatibility layer to read HW and SW ID numbers encoded on the PCB board. After this change the new dm_gpio* API is used for this purpose. Signed-off-by: Lukasz Majewski <lukma@denx.de>

2019-10-08ARM: Update display5_factory_defconfig after switch to DM/DTS and uuu utilityLukasz Majewski
This commit updates the display5_factory_defconfig file after the switch to DM/DTS for this board. Moreover, the VID and PID for SPL running SDP gadget have been updated to allow seamless work with 'uuu' utility from NXP (the imx_usb doesn't work properly after embedding the u-boot proper into fitImage - problem with IVT embedding in FIT). Example to use 'uuu' session: cat << EOF > display5_recovery.lst uuu_version 1.2.135 SDP: boot -f /srv/tftp/SPL SDPU: write -f /srv/tftp/u-boot-dtb.img -addr 0x10000000 SDPU: jump -addr 0x10000000 SDPU: done EOF sudo ./uuu/uuu display5_recovery.lst Signed-off-by: Lukasz Majewski <lukma@denx.de>

2019-10-08DM: WDT: Convert WDT driver to use DM/DTS (including SYSRESET)Lukasz Majewski
This commit enables support for CONFIG_WDT in the U-Boot proper. Moreover, the SYSRESET_WATCHDOG driver is used to support 'reset' command. As SPL is not yet ready for DM conversion, the CONFIG_HW_WATCHDOG is enabled for it. This allows the legacy SPL code to work properly. Signed-off-by: Lukasz Majewski <lukma@denx.de>
