[U-Boot] [PATCH v4 0/3] spl: USB Gadget cleanup

[Stefan Agner]

From: Stefan Agner <stefan.agner@toradex.com>


This patchset cleans up the SPL USB Gadget Kconfig and Makfile.
The first two patches are actual fixes and we might consider to
add these two for the v2016.11 release. The third one adds a new
config option for cleaner structure. I plan to add another USB
function with SPL support which is the reason I looked into
this...

Build tested using buildman for all boards on powerpc mips and
arm. No new errors or warnings:
Building 4 commits for 1072 boards (8 threads, 1 job per thread)
 4044    0  244 /4288   P1022DS_NAND

This patchset is probably most interesting for
am335x_evm_usbspl_defconfig (CONFIG_SPL_USBETH_SUPPORT)
And the board with which SPL DFU support has been introduced
dra7xx_evm_defconfig (CONFIG_SPL_DFU_SUPPORT, not set by default)

A follow-up patchset which moves RAM boot support into a separate
file is in preparation.

Changes in v4:
- Use correct config CONFIG_SPL_RAM_DEVICE to descide whether to add
  BOOT_DEVICE_RAM to linker list.

Changes in v3:
- Fix depends on SPL_USB_GADGET_SUPPORT and use if statement

Changes in v2:
- Use CONFIG_SPL_RAM_SUPPORT to descide whether to compile the
  function in first place.
- Leave DWC3 config in top level SPL Makefile (as U-Boot does)

[U-Boot] [PATCH v4 1/3] spl: add RAM boot device only if it is actually defined

[Stefan Agner]

From: Stefan Agner <stefan.agner@toradex.com>

Some devices (e.g. dra7xx) support loading to RAM using DFU without
having direct boot from RAM support. Make sure the linker list
does not contain BOOT_DEVICE_RAM if CONFIG_SPL_RAM_DEVICE is not
enabled.

Fixes: 98136b2f26fa ("spl: Convert spl_ram_load_image() to use linker list")

[U-Boot] [PATCH v4 2/3] spl: dfu: move DFU Kconfig to SPL Kconfig

[Stefan Agner]

From: Stefan Agner <stefan.agner@toradex.com>

The DFU Kconfig menu entries should be part of the SPL
Kconfig file. Also avoid using the top level Makefile by
moving the config dependent build artifacts to the driver/
and driver/usb/gadget/ Makfiles.

With that, DFU can be built again in SPL if
CONFIG_SPL_DFU_SUPPORT is enabled.

Fixes: 6ad6102246d8 ("usb:gadget: Disallow DFU in SPL for now")
