It likely isn't SPI, unless you tried writing a bootloader to it. SPI is empty OOTB.
Luckily, your PBP probably isn't bricked, but there may be a problem with eMMC or install on it. Have you checked to make sure the eMMC is fully seated on the board? Sometimes, they can get jostled and unseated, causing sporadic issues in booting. You can also try to boot from an SD if you use the internal switch to disable the eMMC. If you can do that, you're certainly not bricked. Once booted through SD you can use the switch to enable the eMMC again, and use a few commands (in the wiki) to rebind the eMMC for writing.
If after restoring or reinstalling to the eMMC, if you'd like to use BSP uboot to get s3 sleep, I'd suggest using pcm720's u-boot with ArgleBargle's script, as outlined in the previously linked wiki section.
