rockusb is a protocol run between host pc and device. it help people get device
info, flash image to device. this patch implement rockusb on device side.
Eddie Cai (9):
usb: ums: split macro and data struct in storage_common.c
usb: ums: split macro and data struct in f_mass_storage.c
usb: ums: merge storage_common.c into f_mass_storage.c
usb: ums: remove static declaration of some ums functions
usb: ums: add functions to set and get usb interface descriptor
usb: ums: add do_extra_command
cmd: add rockusb command
rockchip: config: enable rockusb support on rk3288 based board
rockusb: add a simple readme

+Rockusb (Rockchip USB protocol)
+=====================================================
+
+Overview
+--------
+
+Rockusb protocol is widely used with Rockchip devices.
+It can read/write info, image to/from devices. This
+document briefly describes how to use Rockusb for upgrading
+firmware (e.g. kernel, u-boot, rootfs, etc.).
+
+Tools
+--------
+There are many tools can support Rockusb protocol. rkdeveloptool
+is open source, It is maintained by Rockchip.
+
+Usage
+--------
+The Usage of Rockusb command is
+rockusb <USB_controller> [<devtype>] <devnum>
+e.g. rockusb 0 mmc 0
+rockusb 0 usb 0
+On your U-Boot console, type this command to enter rockusb mode.
+On your host PC. use lsusb command. you should see a usb device
+using 0x2207 as its USB verdor id. Then use rkdeveloptool
+sudo rkdeveloptool wl <BeginSec> <File>
+to flash U-Boot image use command
+sudo rkdeveloptool wl 64 <U-Boot binary>
+There are plenty of Rockusb command. but wl(write lba) and
+rd(reboot) command. These two command can let people flash
+image to device.
+
+To do
+-----
+* Fully support Rockusb protocol

Hi Eddie,
Sorry for late reply - the Easter break.
I would prefer to keep things as they are now.
The reason is that f_mass_storage gadget in Linux has the same file
structure as u-boot -
e.g. ./drivers/usb/gadget/function/storage_common.c in Linux tree.
It would be easier then to update the u-boot to Linux code if needed
(or ported to DM).
Best regards,
Łukasz Majewski

Hi Eddie,
> add functions to set and get usb interface descriptor, so people can
> customize usb interface descriptor
The f_mass_storage USB function is used through the g_dnl code:
./drivers/usb/gadget/g_dnl.c
Other gadget functions - like dfu and thor are using it.
Please consider following this scheme - for example look into the
Samsung's Thor protocol support at:
./drivers/usb/gadget/f_thor.c
Since we managed to add Thor (vendor specific protocol), then it should
be doable to add rockusb as well.
Another good example of this framework reuse is f_fastboot.c to support
Android fastboot protocol.
Please consider if rockchip could be added in the same manner.

To adjust the usb descriptor one can use:
g_dnl_bind_fixup() function (defined at g_dnl.c).
It is used to adjust information added to USB file descriptor - e.g.
board/samsung/common/gadget.c or board/siemens/common/factoryreset.c

I must admit that I'm against mixing things. Let's leave f_mass_storage
for mass storage and add f_rockchip_* for separate function.
If possible we can reuse as much as possible from f_*.c and g_dnl.*
files.

This code should be moved to f_rockchip_* as it is the routine

This patch would need to be adjusted if mentioned earlier changes are
applied.

Reboot is also supported - but there is no unification - though each

IMHO reading images (for backup) would be handy as well.

For me it is OK, to have a minimal subset of commands supported - let's
add the very basic support and extend it latter.

That is the same way i did in my V1 patches. can you review my V1 patches
again and give some comment? that will be easy for me to address your comments
at the same time.

It is in f_rockusb.c in my V1 patch. I think we don't share this macro
with other file. So i don't put it in a .h file. Let me know if you
have further comment.

SoC infor, Storage infor, thins in eFuse like serial number. I did have plan to
add this function. But to keep things simple. I want to add minimum function
first. It will be easy for me to add new function if everybody agree
the framework.

yes, if you only talk about wl command. But there are many other rockusb

I do have plan to add this function. But I would like this minimum set agreed by
everybody. then add more command.
If i implemented all the rockusb command. It will be huge work for me when
i move from V1 to V2 patch.
Please help review my V1 patch. My V3 patch will based on V1 patch.
Let me know if you have more comment.
