52f7d8442e am335x:Handle worst case scenario for Errata 1.0.24
In Errata 1.0.24, if the board is running at OPP50 and has a warm reset,
the boot ROM sets the frequencies for OPP100. This patch attempts to
drop the frequencies back to OPP50 as soon as possible in the SPL. Then
later the voltages and frequencies up set higher.

9721027aae am335x_evm: am33xx_spl_board_init function and scale core frequency
Add a am33xx_spl_board_init (and enable the PMICs) that we may see,
depending on the board we are running on.  In all cases, we see if we
can rely on the efuse_sma register to tell us the maximum speed.  In the
case of Beaglebone White, we need to make sure we are on AC power, and
are on later than rev A1, and then we can ramp up to the PG1.0 maximum
of 720Mhz.  In the case of Beaglebone Black, we are either on PG2.0 that
supports 1GHz or PG2.1.  As PG2.0 may or may not have efuse_sma set, we
cannot rely on this probe.  In the case of the GP EVM, EVM SK and IDK we
need to rely on the efuse_sma if we are on PG2.1, and the defaults for
PG1.0/2.0.

73feefdc1a am33xx: Stop using PHYS_DRAM_1 define
We defined PHYS_DRAM_1 to 0x80000000 (start of DRAM) and then used this

in other places.  Change to directly setting CONFIG_SYS_DRAM_BASE and

c5c7a7c32d am335x_evm: Add support to boot from NOR.
NOR requires that s_init be within the first 4KiB of the image so that
we can perform the rest of the required pinmuxing to talk with the rest
of NOR that we are found on.  When NOR_BOOT is set we save our
environment in NOR at 512KiB and a redundant copy at 768KiB.  We avoid
using SPL for this case and u-boot.bin is written directly to the start
of NOR.

We enclose the DMM-related parts of arch/arm/cpu/armv7/am33xx/emif4.c
with TI81xx checks as at this time U-Boot does not discard unused
sections in the main build and this code relies on functions specific to
(and only provided in) ti81xx-related code.

12d7a47420 am335x: enable falcon boot mode for mmc (raw and fat) and nand
Jump into full u-boot mode if a 'c' character is received on the uart.

We need to adjust the spl bss/malloc area to not overlap with the
loadaddr of the kernel (sdram + 32k), so move it past u-boot instead.

For raw mmc, we store the kernel parameter area in the free space after
the MBR (if used). For nand, we use the last sector of the partition
reserved for u-boot.

This also enables the spl command in the full u-boot so the kernel
parameter area snapshot can be created.

the am335x_evm_uart3 board configuration as introduced
by Andrew Bradfords recent patch series "am33xx: Enable
