This series applies on u-boot/next
It aims at reducing the size taken by the mmc core in the SPL. Recent changes (for which I'm to blame) have bloated the mmc core and have broken platforms that were already tight on code space. This is achieved mostly by compiling out parts of the initialization process that are not required when the SD/MMC write operations are not used.
Using am335x_hs_evm_config and Linaro GCC 6.2-2016.11 toolchain, this series saves 704 bytes of sram (592 bytes of code and 112 bytes of rodata). This doesn't looks like much but it allows building the platform without removing features from its config file (tested with commit d2ac491 ("am335x_hs_evm: Trim options in SPL to reduce binary size") reverted)
Jean-Jacques Hiblot (10): common: do not compile common fastboot code when building the SPL mmc: atmel: when sending a data command, use the provided block size mmc: remove unneeded verification in mmc_set_card_speed() mmc: compile out more code if support for UHS and HS200 is not enabled mmc: reworked version lookup in mmc_startup_v4 mmc: add a Kconfig option to enable the support for MMC write operations mmc: read ssr only if MMC write support is enabled mmc: compile out erase and write mmc commands if write operations are not enabled mmc: don't read the size of eMMC enhanced user data area in SPL mmc: remove hc_wp_grp_size from struct mmc if not needed
