U-Boot needs more than 35 seconds to load the kernel image

[matthiasklein]

Description

U-Boot needs more than 35 seconds to load the kernel image.
My first test was on a Pi Zero W, which takes a similar amount of time with the same SD card.

Steps to reproduce the issue:

1. Build master tree
2. #MACHINE ??= "raspberrypi0-wifi"
   MACHINE ??= "raspberrypi3"
3. ENABLE_UART = "1"
   RPI_USE_U_BOOT = "1"

Describe the results you received:

Boot takes very long: 6954192 bytes read in 36838 ms (183.6 KiB/s)

Describe the results you expected:

Faster boot time.
