Some USB devices cause the USB stack to get stuck with a stall error. This adds a patch which recovers from this situation. This avoids an U-Boot crash when Arduino Mega R3 devices are connected, which cause an USB stall when trying to read the product string.

Subject: [PATCH 2/5] raspberrypi: Disable simple framebuffer support
|
|
|
|
On 4.19 kernels this u-boot driver clashes with bcm2708_fb.
|
|
So let's disable it from here so that we have bcm2708_fb
|
|
enabled in the kernel, just as Raspbian users might expect.
|
|
See https://github.com/raspberrypi/linux/issues/3139
|
|
|
|
Upstream-Status: Inappropriate [configuration]
