Subject: [PATCH 0/2] ARC: [plat-hsdk]: enable on-board SPI peripherals

HSDK board has SPI flash IC and SPI ADC IC. As all SPI-related
blocking changes/fixes are finally applied we can enable them.

Eugeniy Paltsev (2):
ARC: [plat-hsdk]: Enable on-board SPI NOR flash IC
ARC: [plat-hsdk]: Enable on-boardi SPI ADC IC
