- HALs get_rtr_int_idx and get_ip_max_idx return the chip specific router index and number of IPs. This information is static for a chip and doesn't require any input. Hence, update the HAL definition to not require hwpm pointer as an argument. Update definition and references for these HALs. - Add new HAL to get PMA and RTR structure pointers. Implement and update other chip specific functions to use new HAL. - Add new timer macro to check a condition and timeout after given retries. Update necessary code to use new timer macro. - Correct validate_emc_config function to compute correct available mss channel mask based on fuse value. - Update tegra_hwpm_readl and tegra_hwpm_writel macros to assert error value. This way error checks are added at one spot and not sprinkled all over the driver code. - Update get_mem_bytes_put_ptr() and membuf_overflow_status() to return error as function return and accept arguments to return mem_head pointer and overflow status respectively. Add overflow status macros to use throughout driver. Update HAL definition and references accordingly. - conftest is only compiled for OOT config atm. Add OOT config check to include conftest header.
