+From: Nikita Yushchenko <nyushchenko at dev.rtsoft.ru>
+Subject: [PATCH] usb: pci-quirks: do not access OHCI_FMINTERVAL register on ULI hw
+
+This access causes hang on Freescale P2020DS board (that has OHCI
+provided by ULI 1533 chip).
+
+Since preserving OHCI_FMINTERVAL was originally done only for NVIDIA
+hardware and only later (in c6187597) was turned unconditional, and
+c6187597 commit message again mentions only NVIDIA, I think it should be
+safe to disable preserving OHCI_FMINTERVAL if device vendor is ULI.

+You'll need to program the files created by buildroot into the flash.
+The fast way is to tftp transfer the files via one of the network interfaces.
+
+Alternatively you can transfer the files via serial console with an Ymodem
+file transfer from your terminal program by using a "loady" command
+from the u-boot prompt instead of the "tftp ..." commands stated below.
+Beware that serial console file transfers are quite slow!
+
+1. Program the DTB to NOR flash
+
+   => tftp ${loadaddr} p2020ds.dtb
+   => erase 0xeff00000 0xeff7ffff
+   => cp.b ${loadaddr} 0xeff00000 ${filesize}
+
+2. Program the kernel to NOR flash
+
+   => tftp ${loadaddr} uImage
+   => erase 0xec000000 0xec3fffff
+   => cp.b ${loadaddr} 0xec000000 ${filesize}
+
+3. Program the root filesystem to NOR flash
+
+   => tftp ${loadaddr} rootfs.jffs2
+   => erase 0xec400000 0xeeffffff
+   => cp.b ${loadaddr} 0xec400000 ${filesize}
+
+4. Booting your new system
+
+   => setenv jffs2boot 'setenv bootargs root=/dev/mtdblock4 rootfstype=jffs2 rw console=ttyS0,115200;bootm ec000000 - eff00000'
+
+   If you want to set this boot option as default:
+
+   => setenv bootcmd 'run jffs2boot'
+   => saveenv
+
+   ...or for a single boot:
+
+   => run jffs2boot
+
+   You can login with user "root".
