U-Boot mostly uses hex for value input, largely because addresses are much easier to understand in hex.

But in some cases a hex value is requested, but it is more convenient to provide a decimal value. This may be because the value comes from another source, where its base cannot be controlled.

This series adds support for a 0m prefix to indicate a decimal number. The letter 'm' is chosen because:

• 'm' as in deciMal
• cannot use a-f since they indicate a hex value (e.g. 0d would be ambiguous)
• 'l' is harder to read since 1 and l look similar (0l123)
• 't' (as in ten) seems a bit obscure

NetBSD ddb(4) uses 0t as a prefix for base 10.
