5ce904b20f Introduce PLATFORM_ENTER, replacing the old PLATFORM_SETUP for DFU mode
setup. PLATFORM_SETUP now performs early general platform setup, such as
turning off the watchdog.

- fw/boot/boot.c (main): the first thing we do is to run PLATFORM_SETUP
- fw/boot/boot.c (boot_loader): instead of PLATFORM_SETUP, run
  PLATFORM_ENTER

fd09655773 Requests following a rejected SETUP requests failed too, which sometimes
produces user-visible errors and may confuse implementations. (E.g., when
probing for an unimplemented feature and subsequently being greeted by a
timeout.)

- fw/comon/usb.c (handle_setup): set SOPRDY when answering a request error
  with a stall, according to the example in AN139. This seems to eliminate
  the timeouts observed in requests following after bad requests.
- fw/boot/boot.c (run_payload): described how the host is expected to
  respond to the device resetting its USB stack

3f5ec8aa9e Use config.h as the main source of configuration data. Fixed some boot.c
glitches.

- fw/boot/boot.c, fw/boot/dfu.c: include config.h for platform defines
- fw/common/Makefile.common: add $(F32XBASE)/fw/common to include search
  path
- fw/boot/boot.c: define dummy for uart_init if no debugging is enabled
- fw/boot/boot.c (PLATFORM_EXIT): typo PLAYFORM_EXIT
- fw/boot/boot.c (run_payload): rename BOOT_SETUP to PLATFORM_SETUP
- fw/boot/dfu.c (device_descriptor): use USB_PRODUCT instead of
  USB_PRODUCT_IDBG_DFU
- fw/boot/config.h: removed for now. Might bring it back later as template.
- fw/boot/version.h: moved to fw/common/
- fw/common/Makefile.system: remove serial setup

fcfaec399a Move platform-specific boot loader configuration into macros.
- fw/boot/boot.c (boot_loader): moved GTA-specific pull-up disable and
  I2C_SDA_PULL enable into macro PLATFORM_SETUP
- fw/boot/boot.c (run_payload): moved GTA-specific pull-up enable and
  I2C_SDA_PULL disable into macro PLATFORM_EXIT
- fw/boot/boot.c (boot_loader): moved GTA-specific I2C_SDA probe into macro
  PLATFORM_TEST
- fw/common/Makefile.common: removed all references to dependencies on
  .target. The caller is now responsible for these.
- fw/boot/dfu.c: don't include idbg/usb-ids.h; USB_VENDOR and USB_PRODUCT
  are now passed via macros
