# Raspberry Pi5 bootloader EEPROM release notes

## 2026-04-30: 2712: arm_boot: Enable turbo clocks before loading the kernel (latest)

* arm_display: Correct logging message hdmi_pixel_freq_limit
Noticed in a raspinfo log file.
* Increase default v3d frqeuency on 2712d0
* pi5: arm_boot: Enable turbo clocks before loading the kernel
Originally, for the entire boot ran at the idle-operating
point. Subsequently, the default for intial_turbo was changed so
that the kernel is started with turbo-clocks unless disabled
via config.txt.
This change enables the turbo-clocks as soon as it is safe as soon
as the turbo voltage has been calibrated to speedup kernel loading
and device-tree processing.
This reduces boot time by approximately 1 second on a Pi5 booting
from NVMe.
