There are some changes to support ARM64 i.MX8M platform in this patches: 1. The hab_rvt base and function vectors are different as i.MX6/7 2. Need to bypass an workaround for i.MX6 to fix problem in MMU. 3. The x18 register needed save & restore before calling any HAB API. According to ARM procedure call spec, the x18 is caller saved when it is used as temporary register. So calling HAB API may scratch this register, and cause crash once accessing the gd pointer. On ARMv7, the r9 is callee saved when it is used as variable register. So no need to save & restore it. 4. Add SEC_CONFIG fuse for iMX8M When current EL is not EL3, the direct calling to HAB will fail because CAAM/SNVS can't initialize at non-secure mode. In this case, we use SIP call to run the HAB in ATF. Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com> |
