2019-11-05imx: imx8m: fix boot when CONFIG_$(SPL_)CLK not definedPeng Fan
When CONFIG_$(SPL_)CLK not defined, the clock controller device not exist, so to avoid boot failure for platform not have CONFIG_$(SPL_)CLK, add a check. Reviewed-by: Patrick Wildt <patrick@blueri.se> Tested-by: Patrick Wildt <patrick@blueri.se> Signed-off-by: Peng Fan <peng.fan@nxp.com>
2019-11-05imx8mn: add get_boot_devicePeng Fan
No ROM INFO structure on iMX8MN, use new ROM API to get boot device from ROM. Signed-off-by: Peng Fan <peng.fan@nxp.com>
2019-11-05imx8mn: set BYPASS ID SWAP to avoid AXI bus errorsPeng Fan
Set the BYPASS ID SWAP bit (GPR10 bit 1) in order for GPU not to generated AXI bus errors with TZC380 enabled. Signed-off-by: Peng Fan <peng.fan@nxp.com>
2019-11-05imx8mn: support get_cpu_revPeng Fan
Add a dummy cpu type and support get_cpu_rev for i.MX8MN Signed-off-by: Peng Fan <peng.fan@nxp.com>
2019-11-03imx8m: imx8mq: get chip rev for B1 revisionPeng Fan
The i.MX8MQ B1 uses OCOTP_HW_OCOTP_READ_FUSE_DATA register for chip id. It returns a magic number 0xff0055aa. update get_cpu_rev to support it, and enable ocotp clock to access ocotp. Signed-off-by: Peng Fan <peng.fan@nxp.com>
2019-10-08imx: replace CONFIG_SECURE_BOOT with CONFIG_IMX_HABStefano Babic
CONFIG_SECURE_BOOT is too generic and forbids to use it for cross architecture purposes. If Secure Boot is required for imx, this means to enable and use the HAB processor in the soc. Signed-off-by: Stefano Babic <sbabic@denx.de>
2019-10-08imx8m: soc: probe clock device in arch_cpu_init_dmPeng Fan
Because we need to get cpu freq in print_cpuinfo at very early stage, so we need to make sure the ccm be probed. Signed-off-by: Peng Fan <peng.fan@nxp.com>
2019-10-08imx8m: restrict reset_cpuPeng Fan
Make reset_cpu only visible when CONFIG_SYSRESET not defined or CONFIG_SPL_BUILD. Signed-off-by: Peng Fan <peng.fan@nxp.com>
2019-10-08imx8m: soc: enable SCTR clock before timer initPeng Fan
To i.MX8MM SCTR clock is disabled by ROM, so before timer init need to enable it. To i.MX8MQ, it does not hurt the clock is enabled again. Signed-off-by: Peng Fan <peng.fan@nxp.com>
2019-10-08imx8m: Configure trustzone region 0 for non-secure accessYe Li
Set trustzone region 0 to allow both non-secure and secure access when trust zone is enabled. We found USB controller fails to access DDR if the default region 0 is secure access only. Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>

2019-10-08imx8m: Fix MMU table issue for OPTEE memoryPeng Fan
When running with OPTEE, the MMU table in u-boot does not remove the OPTEE memory from its settings. So ARM speculative prefetch in u-boot may access that OPTEE memory. Due to trust zone is enabled by OPTEE and that memory is set to secure access, then the speculative prefetch will fail and cause various memory issue in u-boot. The fail address register and int_status register in trustzone has logged that speculative access from u-boot. Signed-off-by: Peng Fan <peng.fan@nxp.com>
2019-10-08imx: add get_cpu_rev support for i.MX8MMPeng Fan
