2022-04-26mmc: fsl_esdhc_spl: pre-PBL: implement redundancy supportPali Rohár
QorIQ pre-PBL BootROM scans first 24 SD card sectors (each with fixed 512 bytes length) for boot signature. Implement same redundancy behavior in fsl_esdhc_spl driver to allow loading proper U-Boot when boot sector is not the first one.

2022-04-26mmc: fsl_esdhc_spl: Call mmc_init() before booting from SD cardPali Rohár
If env is stored on SD card then U-Boot SPL automatically calls mmc_init() before it is going to load proper U-Boot from SD card. If env is not stored on SD card then U-Boot SPL fails to read proper U-Boot from SD card due to missing mmc_init() call. So add missing mmc_init() call into fsl_esdhc_spl's mmc_boot() function. It fixes booting from SD card on P2020 boards without env support in SPL. mmc_init() returns early if card was already initialized, so there is no issue with calling this function more times.

2022-04-26mmc: fsl_esdhc_spl: pre-PBL: fix determining U-Boot sizePali Rohár
In pre-PBL header is stored size of code which BootROM copies from SD card to L2/SRAM. This size has upper limit of L2 cache size. In most cases this is size of U-Boot SPL or size of L2 cache. Therefore this size in pre-PBL header cannot be used for determining size of proper U-Boot. So always use CONFIG_SYS_MMC_U_BOOT_SIZE for determining size of proper U-Boot which stored on SD card.

Pre-PBL BootROMs (MPC8536E, MPC8569E, P2020, P1011, P1012, P1013, P1020, P1021, P1022) require custom BOOT signature on sector 0 and MBR/DBR signature is not required at all. So add check for BOOT signature and remove check for MBR/DBR.

2022-04-18dm: core: Deal with a wrinkle with linker listsSimon Glass
When every member of a linker list is aligned by the compiler, we can no longer rely on the sizeof of the struct to determine the number of entries. For example, if the struct size is 0x90 but every entry is aligned to 0xa0 by the compiler, the linker list entries takes more space in memory and the calculation of the number of entries is incorrect. For example, we may see 0x12 entries when there are only 0x11. This is a real problem. There may be a general solution, although I cannot currently think of one. So far it only bites with OF_PLATDATA_RT which creates a pointer to each entry of the 'struct udevice' linker_list. This does not happen without that option, so it only affects SPL. Work around it by manually calculating the aligned size of struct udevice, then using that for the n_ent calculation.
