| 19 | Support for all ARM1176-/BCM2835-based Raspberry Pi variants, such as |
| 20 | the A, A+, B, B+, Compute Module, and Zero. This option cannot |
| 21 | support BCM2836/BCM2837-based Raspberry Pis such as the RPi 2 and |
| 22 | RPi 3 due to different peripheral address maps. |
| 23 | |
| 24 | This option creates a build targetting the ARM1176 ISA. |

| 31 | Support for all BCM2836-based Raspberry Pi variants, such as |
| 32 | the RPi 2 model B. |
| 33 | |
| 34 | This option also supports BCM2837-based variants such as the RPi 3 |
| 35 | Model B, when run in 32-bit mode, provided you have configured the |
| 36 | VideoCore firmware to select the PL011 UART for the console by: |
| 37 | a) config.txt should contain dtoverlay=pi3-miniuart-bt. |
| 38 | b) You should run the following to tell the VC FW to process DT when |
| 39 | booting, and copy u-boot.bin.img (rather than u-boot.bin) to the SD |
| 40 | card as the kernel image: |
| 41 | |
| 42 | path/to/kernel/scripts/mkknlimg --dtok u-boot.bin u-boot.bin.img |
| 43 | |
| 44 | This works as of firmware.git commit 046effa13ebc "firmware: |
| 45 | arm_loader: emmc clock depends on core clock See: |
| 46 | https://github.com/raspberrypi/firmware/issues/572". |
| 47 | |
| 48 | This option creates a build targetting the ARMv7/AArch32 ISA. |
