Andrew Rice 6958f6638e usb_storage: report read-only drives as write protected
A target that defines HAVE_STORAGE_READONLY provides storage_readonly(),
and USB mass storage reports such a drive write protected: MODE SENSE
sets the WP bit, and WRITE(10) and WRITE(16) fail with DATA PROTECT /
WRITE PROTECTED before taking data, so a host mounts it read-only
instead of failing each write as a medium error. Only NAND storage wires
it up so far.

The iPod Nano 3G, added in the changes that follow, defines it: its FTL
mounts read-only in the bootloader and after a failed commit, and the
NAND check image is always read-only.

Built for the Nano 3G (bootloader, check image, firmware) without new
warnings. On hardware, Linux and Windows hosts have read the
always-read-only check image over USB; no host write has been made to a
read-only drive.

AI provenance: developed with Claude Opus 5 (Anthropic), used through
Claude Code. The model wrote most of the code and this message under
Andrew Rice's direction. Any hardware testing described above was
carried out by Andrew Rice, who is responsible for this change.

Build Your Own Rockbox

1. Clone 'rockbox' from git (or extract a downloaded archive).

   $ git clone git://git.rockbox.org/rockbox

     or

   $ tar xJf rockbox.tar.xz

2. Create a build directory, preferably in the same directory as the firmware/
   and apps/ directories. This is where all generated files will be written.

   $ cd rockbox
   $ mkdir build
   $ cd build

3. Make sure you have mips/m68k/arm-elf-gcc and siblings in the PATH. Make sure
   that you have 'perl' in your PATH too. Your gcc cross compiler needs to be
   a particular version depending on what player you are compiling for. These
   can be generated using the rockboxdev.sh script in the /tools/ folder of the
   source.

   $ which arm-elf-eabi-gcc
   $ which perl

4. In your build directory, run the 'tools/configure' script and enter what
   target you want to build for and if you want a debug version or not (and a
   few more questions). It'll prompt you. The debug version is for making a
   gdb version out of it. It is only useful if you run gdb towards your target
   Archos.

   $ ../tools/configure

5. *ploink*. Now you have got a Makefile generated for you.

6. Run 'make' and soon the necessary pieces from the firmware and the apps
   directories have been compiled, linked and scrambled for you.

   $ make
   $ make zip

7. unzip the rockbox.zip on your music player, reboot it and
   *smile*.

If you want to build for more than one target, just create several build
directories and create a setup for each target:

   $ mkdir build-fuzeplus
   $ cd build-fuzeplus
   $ ../tools/configure

   $ mkdir build-xduoox3
   $ cd build-xduoox3
   $ ../tools/configure
