The fsl_esdhc driver was for Freescale eSDHC on MPC83XX/MPC85XX initially. The later QoriQ series PowerPC processors (which were evolutions of MPC83XX/MPC85XX), QorIQ series ARM processors, and i.MX series processors were using this driver for their eSDHCs too.
For the two series processors, the eSDHCs are becoming more and more different. We should have split it into two drivers, like them (sdhci-of-esdhc.c/sdhci-esdhc-imx.c) in linux kernel.
It's ideal to keep common part for reusing. However, it's hard to find out a little which could be reused. The truth is there will be more and more different registers, bits and operatiing processes. Even some code is common now, it may have to be split in the future. So let's just split is as two drivers.
Patch #2 just created a fsl_esdhc_imx driver which was a copy of fsl_esdhc driver for i.MX processors. Patch #3 converted i.MX platforms to use fsl_esdhc_imx. Patch #4 and #5 just dropped useless code for the two driver. There are still many cleaning up works needed to be done in the future, because the eSDHC driver is mess for a long time. Since I'm only owner for QorIQ eSDHC driver, I dropped only a little things which I'm sure for fsl_esdhc_imx. Let i.MX eSDHC owner do futhur cleaning up.
Travis-CI build: https://travis-ci.org/yangbolu1991/u-boot-test/builds/548024197
--- Changes for v6: - Rebased. - Applied to two new i.MX boards phycore_pcl063_ull/pico-imx7d_bl33. Changes for v7: - Rebased on https://gitlab.denx.de/u-boot/u-boot.git. - Added Reviewed-by. Changes for v8: - Moved CONFIG_FSL_ESDHC into defconfig for colibri-imx8x/ls1028a/apalis-imx8 platforms introduced recently. - Applied eSDHC i.MX driver to colibri-imx8x/apalis-imx8 platforms.
Yangbo Lu (5): Move CONFIG_FSL_ESDHC to defconfig mmc: split fsl_esdhc driver for i.MX Convert to use fsl_esdhc_imx for i.MX platforms mmc: fsl_esdhc: drop i.MX code mmc: fsl_esdhc_imx: drop useless code
