* stm32: convert to CONFIG_CHIP_MEMORY_REGIONSVincent Palatin2018-03-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the former special case for USB RAM Add additional RAM regions for STM32H7. For USB RAM, add an explicit alignment directive to ensure we always meet the 8-byte boundary hardware constraint for the BTABLE. This was already true because we put the .usb_ram.btable section first. I keep this property by alpha-sorting the sections but makes it more explicit by adding a 2-digit numeric prefix: e.g. 00_firstsection, 99_lastsection.

TEST=build all targets with and without the patch and verify that all smap files are identical.

* chip/stm32/usb_hid_keyboard: add dynamic backlight detection supportWei-Ning Huang2017-12-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | In order to make a single hammer image support both base with and without keyboard backlight. We need a way to dynamically determine if backlight is present, and send the correct HID descriptors. This is done through declaring two HID descriptors and return the correct one depending on whether or not the backlight is present. BRANCH=none BUG=b:67722756 TEST=On reworked board with pull-down on backlight pin, USB descriptor has backlight HID report descriptor, and is functional. TEST=On old board with both pull-up and pull-down (equivalent to having pull-up only, i.e. no backlight) USB descriptor does not have backlight HID report descriptor Change-Id: Ie3eac9b3d4cd749308ccfb96a7db469701f9793b Signed-off-by: Nicolas Boichat <drinkcat@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/770600 Reviewed-by: Vincent Palatin <vpalatin@chromium.org>
* stm32/usb: Patching framework for USB descriptorsNicolas Boichat2017-12-121-0/+21
| | | | | | | | | | | | | | | | | | In some cases, we want to be able to dynamically modify a few bytes in the USB descriptor (in our case, length of referenced items), but it could also be other things like flags. These 2 new functions allow to keep all the USB descriptor in flash, and modify these few bytes before writing them in the USB buffer. BRANCH=none BUG=b:37447752 TEST=Flash hammer, USB descriptors are valid.

* chip/stm32/usb: Replace reset handler by generic event handlerNicolas Boichat2017-08-161-5/+22
| | | | | | | | | | | | | | | | | | | Some USB interface handlers need to know when USB has been successfully resumed after a wake event. For example, this is useful so that HID keyboard can send the events at the right time. BRANCH=none BUG=b:35775048 TEST=Using USB HID keyboard patches to queue keys in a FIFO: After USB autosuspends, press a single key and hold it. Without this patch the endpoint data only gets reloaded on the _next_ event. TEST=On hammer, I2C passthrough still works.

This moves the STM32-specific code out of the common header file and into the chip directory where it belongs. Note that this doesn't actually change the code for non-STM32 SoCs; that will happen in a separate CL for clarity.
