v1.10

Raspberry Pi 4 UEFI Firmware v1.10

• Remove internal Device Tree (was unused on the Pi 4 anyway since an external one is needed by start4.elf to initialize the UARTs and other things) [tianocore/edk2-platforms@be2ed5e]
• Fix SPI and UART ACPI devices [tianocore/edk2-platforms@f12e1c0
• Fix PWM ACPI devices [tianocore/edk2-platforms@d45d873]

v1.9

Raspberry Pi 4 UEFI Firmware v1.9

• Update to TF-A v2.3 [tianocore/edk2-non-osi@96ec764]
• Fix an ASSERT being produced with the DEBUG version [tianocore/edk2-platforms@f09ea1a]

v1.8

Raspberry Pi 4 UEFI Firmware v1.8

• Switch to common GraphicsConsoleDxe [tianocore/edk2-platforms@4014ed2]

v1.7

Raspberry Pi 4 UEFI Firmware v1.7

• Fix ACPI interrupt values [tianocore/edk2-platforms@f8b5562]
• Improve ACPI tables [tianocore/edk2-platforms@c03fe68, tianocore/edk2-platforms@fcc2a81, etc.]
• Add PPTT ACPI table [tianocore/edk2-platforms@6beb169]

v1.6

Raspberry Pi 4 UEFI Firmware v1.6

• Enable HTTP/HTTPS boot [tianocore/edk2-platforms@3daa701]
  IMPORTANT: This will not work with the internal network card, because the firmware does not have a driver for it yet. This means that you currently need to use an external network interface, such as a USB one, to use this feature.
• Improve CPU Frequency menu and use a default frequency of 1.5 GHz [tianocore/edk2-platforms@c9f3f68]
• Enable additional early serial output [ccf4034]

v1.5

Raspberry Pi 4 UEFI Firmware v1.5

• Fix a bug in 3 GB RAM Limit for 1 GB and 2 GB Raspberry Pi 4 models [tianocore/edk2-platforms@d1406c6]
• Report effective memory being used in UEFI setup [tianocore/edk2-platforms@28d2f4e]
• Reclaim some unused memory back [tianocore/edk2@d6607d8 and tianocore/edk2-platforms@91ed4f9]
• Fix use of external .dtb's [tianocore/edk2-platforms@828fcbf]

Be mindful that the Device Tree addresses in config.txt have changed with this release of the firmware, so make sure to update any device_tree_address= and device_tree_end= lines in your config.txt to use the new addresses (0x1f0000 and 0x200000 respectively) if you don't use the one from the release archive.

v1.4

Raspberry Pi 4 UEFI Firmware v1.4

• Add user configurable option to enable/disable 3 GB RAM Limit [tianocore/edk2-platforms@874750a]
• Add user configurable option to enable/disable the provision of a Device Tree (to force ACPI) [tianocore/edk2-platforms@da7cb41]
• Improve platform configuration layout [tianocore/edk2-platforms@dac18ca]

v1.3

Raspberry Pi 4 UEFI Firmware v1.3

• Factorize RPi3/RPi4 ACPI tables.
  This update shouldn't have much of any user-noticeable changes besides the ones from [tianocore/edk2-platforms@223bfea]

v1.2

Raspberry Pi 4 UEFI Firmware v1.2

• Fix packet losses and network instability by switching to rgmii-rxid for phy-mode [tianocore/edk2-platforms@5250e8b]

v1.1

Raspberry Pi 4 UEFI Firmware v1.1

• Add Genet MAC address population [tianocore/edk2-platforms@d1a3240, tianocore/edk2-platforms@885a686, tianocore/edk2-platforms@3f0d14b]
• Add Genet ACPI bindings [tianocore/edk2-platforms@cc7a0c6]
• Fix SDHC ACPI interrupts [tianocore/edk2-platforms@314c45b]
• Fix Serial Number population [tianocore/edk2-platforms@9369b01]
• Improve VideoCore firmware version reporting [tianocore/edk2-platforms@180c613]
• Automatically switch between PL011 and miniUART according to the overlay in config.txt [tianocore/edk2-platforms@bfe3483, tianocore/edk2-platforms@41c1d9b]
