This series aims to make it easier to measure boot performance, particularly aimed at rockpro64. It includes the following:
- enabling bootstage on rockpro64 (TPL, SPL, U-Boot proper) - minor fixes and tidy-ups for tracing - minor FDT code tidy-ups
It also reverts a patch which slows down the boot by 30ms. This revert was requested some time ago but with this series we have the data showing the impact.
Changes in v1: - Add detail of impact
Simon Glass (14): trace: Use notrace for short arm: Support trace on armv8 tpm: Add a proper Kconfig option for crc8 in SPL fdt: Avoid exporting fdtdec_prepare_fdt() fdt: Drop ifdefs in fdtdec_prepare_fdt() fdt: Pass the device tree to fdtdec_prepare_fdt() fdt: Check for overlapping data and FDT trace: Move trace pointer to data section mkimage: Add a few more messages for FIT failures trace: Adjust flags in proftool trace: Update trace-format generator for newer version trace: Don't require TIMER_EARLY rockchip: Enable bootstage on rockpro64 Revert "fdtdec: drop needlessly convoluted CONFIG_PHANDLE_CHECK_SEQ"
