[PATCHv2 0/5] Fix wlcore config firwmare annoyances

[Tony Lindgren]

Hi all,

Here are some patches to fix the firmware loading for wl12xx/wl18xx
when the same rootfs is used on multiple WLAN chip variants.

Changes since v1:

- Fix copy paste typo for the SPI related changes as noted by
  Kalle Valo

- Fix uninitialized ret variable warning as noted by Kalle Valo

Regards,

Tony

[PATCH 1/5] wlcore: Prepare family to fix nvs file handling

[Tony Lindgren]

Move struct wilink_family_data to be available for all TI WLAN
variants. And fix familiy typo, it should be just family.

Looks like wl12xx use two different nvs.bin files and wl18xx
uses a different conf.bin file.

[PATCH 4/5] wlcore: Fix config firmware loading issues

[Tony Lindgren]

Booting multiple wl12xx and wl18xx devices using the same rootfs is
a pain. You currently have to symlink the right nvs file depending
on the wl12xx type.

For example, with wl1271-nvs.bin being a symlink to wl127x-nvs.bin
by default and trying to bring up a wl128x based device:

wlcore: ERROR nvs size is not as expected: 1113 != 912
wlcore: ERROR NVS file is needed during boot
wlcore: ERROR NVS file is needed during boot
wlcore: ERROR firmware boot failed despite 3 retries

Note that wl18xx uses a separate config firmware wl18xx-conf.bin
that can be generated with tools using the following two git repos:

git.ti.com/wilink8-wlan/18xx-ti-utils
git.ti.com/wilink8-wlan/wl18xx_fw

So let's not configure the nvs file for wl18xx as it's not needed
AFAIK. If it turns out that we also need the nvs file for wl18xx,
we can just add it to the config firmware data for wl18xx.

Let's fix the issue by using the chip specific config firmware
data, and make sure we produce understandable warnings if something
is missing.
