[XL] Change in coreboot[main]: soc/mediatek/common/dp: Move common functions to dptx_hal_common.c
by Yidi Lin (Code Review) 06 Jan '25

06 Jan '25

Attention is currently required from: Hung-Te Lin, Yu-Ping Wu. Yidi Lin has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/85861?usp=email ) Change subject: soc/mediatek/common/dp: Move common functions to dptx_hal_common.c ...................................................................... soc/mediatek/common/dp: Move common functions to dptx_hal_common.c Move the functions that can be shared with MT8196 to dptx_hal_common.c. The exsisting DP_WRITE1BYTE is used for the bit operation with the mask 0xFF. Adding a new macro DP_CLRSETBITS for the bit operation whose mask is not 0xFF. This macros is prepared for MT8196 because its underly API for DP_WRITE1BYTE and DP_CLRSETBITS is not mtk_dp_write_byte. Therefore, this patch also replaces mtk_dp_write_byte with DP_CLRSETBITS.
