[PATCH 0/3] Update riscv's SYS_BOOTM_LEN to the most commonly used value.

[Martin Herren]

The most commonly used SYS_BOOTM_LEN for riscv is 0x4000000 which is
used in 25 of the current defconfigs.

The previous default config value of 0x800000 was only used in 8
defconfigs.

This patch sets the default to this value.

Command used to get the stats of the used values on RISCV defconfigs:

```
grep -l "CONFIG_RISCV=y" configs/* | \
 xargs -I {} sh -c "grep -H CONFIG_SYS_BOOTM_LEN {} || echo {}:DEFAULT" | \
 cut -d ':' -f 2 | sort | uniq -c
```


Martin Herren (3):
  riscv: Set SYS_BOOTM_LEN explicitly to 0x800000
  riscv: Set SYS_BOOTM_LEN default to 0x4000000
  riscv: Remove default SYS_BOOTM_LEN from defconfig
