Although this is indirect via referencing a tool that gets materials from master. See: = https://www.raspberrypi.org/documentation/raspbian/applications/rpi-update= .md There are also stable and next branches, next being the progression toward the next stable. There are also tagged officially-identified versions. (eeprom firmware is not handled the same as this and is not covered here.) It looks to me like the following are the firmware changes since stable and the most recent tag: 2020-Dec-01 (I'm unsure of the timing/status of this one vs. stable or the most recent tag: same day) firmware: Switch DA9121 PMIC to PWM mode when ARM > 600 MHz 2020-Dec-8 or 9 (9 being the Hexxeh copy): firmware: arm_dt: Handle parent interrupt controllers when masking firmware: config: Add cm4 and pi400 config section filters firmware: MMAL/IL/ISP component: Set the ISP boost frequency once on = open firmware: sdcard: Remove legacy NOOBS support to support booting from = primary partition 4 firmware: arm_loader: Move 2711 RAM to PCIe address 16GB firmware: video_decode: Add parameter to disable timestamp validation firmware: Imx477 camera tuning fixes 2020-Dec-14 or 15: firmware: Use DMA40 for PWM audio firmware: imx477: Replace existing 720p120 mode with a new 1332x990 = 120fps mode firmware: arm_loader: Allow max_framebuffers=3D0 to disable framebuffers 2020-Dec-15: firmware: dmalib: Allow sdcard to borrow channel 6 (I omit the kernel-only update notes.) So: There are things like moving the 2711 RAM PCIe address and putting channel 6 to use for the sdcard and using DMA40 for PWM audio. But I do not claim to understand the implications. NOTE: The above are in branch next as well as master. The most recent tag is at: https://github.com/raspberrypi/firmware/commits/1.20201201 This is likely what is officially distributed for general use. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
