[PATCH 1/2] timers: atmel_tcb: introduce CONFIG_SPL_ATMEL_TCB

Eugen Hristev eugen.hristev at microchip.com
Mon Apr 4 10:35:50 CEST 2022


This commit allows the ATMEL_TCB driver to be unselected in SPL and be
selected in u-boot proper. The SPL can use a different timer.
By having a separate Kconfig for ATMEL_TCB in SPL, the size of the SPL
decreases by 1 KByte.
