* CPU error bits in BOOT_ERROR registers
*
* CPU_BOOT_ERR0_DRAM_INIT_FAIL DRAM initialization failed.
* DRAM is not reliable to use.
*
* CPU_BOOT_ERR0_FIT_CORRUPTED FIT data integrity verification of the
* image provided by the host has failed.
*
* CPU_BOOT_ERR0_TS_INIT_FAIL Thermal Sensor initialization failed.
* Boot continues as usual, but keep in
* mind this is a warning.
*
* CPU_BOOT_ERR0_DRAM_SKIPPED DRAM initialization has been skipped.
* Skipping DRAM initialization has been
* requested (e.g. strap, command, etc.)
* and FW skipped the DRAM initialization.
* Host can initialize the DRAM.
*
* CPU_BOOT_ERR0_BMC_WAIT_SKIPPED Waiting for BMC data will be skipped.
* Meaning the BMC data might not be
* available until reset.
*
* CPU_BOOT_ERR0_NIC_DATA_NOT_RDY NIC data from BMC is not ready.
* BMC has not provided the NIC data yet.
* Once provided this bit will be cleared.
*
* CPU_BOOT_ERR0_NIC_FW_FAIL NIC FW loading failed.
* The NIC FW loading and initialization
* failed. This means NICs are not usable.
*
* CPU_BOOT_ERR0_SECURITY_NOT_RDY Chip security initialization has been
* started, but is not ready yet - chip
* cannot be accessed.
*
* CPU_BOOT_ERR0_SECURITY_FAIL Security related tasks have failed.
* The tasks are security init (root of
* trust), boot authentication (chain of
* trust), data packets authentication.
*
* CPU_BOOT_ERR0_EFUSE_FAIL Reading from eFuse failed.
* The PCI device ID might be wrong.
*
* CPU_BOOT_ERR0_PRI_IMG_VER_FAIL Verification of primary image failed.
* It mean that ppboot checksum
* verification for the preboot primary
* image has failed to match expected
* checksum. Trying to program image again
* might solve this.
*
* CPU_BOOT_ERR0_SEC_IMG_VER_FAIL Verification of secondary image failed.
* It mean that ppboot checksum
* verification for the preboot secondary
* image has failed to match expected
* checksum. Trying to program image again
* might solve this.
*
* CPU_BOOT_ERR0_PLL_FAIL PLL settings failed, meaning that one
* of the PLLs remains in REF_CLK
*
* CPU_BOOT_ERR0_DEVICE_UNUSABLE_FAIL Device is unusable and customer support
* should be contacted.
*
* CPU_BOOT_ERR0_BOOT_FW_CRIT_ERR Critical error was detected during
* the execution of ppboot or preboot.
* for example: stack overflow.
*
* CPU_BOOT_ERR0_BINNING_FAIL Binning settings failed, meaning
* malfunctioning components might still be
* in use.
*
* CPU_BOOT_ERR0_TPM_FAIL TPM verification flow failed.
*
* CPU_BOOT_ERR0_TMP_THRESH_INIT_FAIL Failed to set threshold for tmperature
* sensor.
*
* CPU_BOOT_ERR_EEPROM_FAIL Failed reading EEPROM data. Defaults
* are used.
*
* CPU_BOOT_ERR0_ENABLED Error registers enabled.
* This is a main indication that the
* running FW populates the error
* registers. Meaning the error bits are
* not garbage, but actual error statuses.
