* Remove linker lists (LGAs) from SPL linker scriptsAlbert ARIBAUD2013-03-122-12/+0
| | | | | | | | | | | | Many SPL linker scripts needlessly include linker lists (aka LGAs). Remove them whenever possible; keep it only in the seven am335x_evm variants (am335x_evm, am335x_evm_uart[1-5], am335x_evm_spiboot), where there is actual content in output section .u_boot_list. This commit keeps all u-boot.bin and u-boot-spl.bin in ARM targets byte-identical. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

The eth_getenv_enetaddr_by_index method will validate the MAC addr and if none is set in the environment 0 will be returned. Set the MAC from the eeprom if no valid address is found in environment.

This functionality is reimplemented multiple times in the code, thus make one common implementation. Moreover, make it a switch(), since the SSP ports are not mapped in such nice linear fashion on MX23, therefore having it a switch will simplify things there.

This covers the code sequence from setting up the initial stack to calling into board_init_r(). Also, rewrite the C runtime setup and make functions board_init_*() and relocate_code() behave according to normal C semantics (no jumping across the C stack any more, etc). Some SPL targets had to be touched because they use start.S explicitly or for some reason; the relevant maintainers and custodians are cc:ed. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

| | | | | | | | | | | | | | | | The MMC driver appropriate for the i.MX25 is fsl_esdhc, which has nothing to do with mxcmmc. Also, each eSDHC instance has a dedicated clock, so gd->sdhc_clk must be set accordingly. This is good for the case only a single SDHC instance is used (initialization made with fsl_esdhc_mmc_init()). A future patch will fix the multi-instance use case (initialization made directly with fsl_esdhc_initialize()).
