[RFC PATCH] ppc/spapr: Change printf format to %HWADDR_PRId for MIN_RMA_SLOF

[Aditya Gupta <adityag@linux.ibm.com>]

Currently starting a pSeries machine, with lesser than 128MiB shows
below error:

    qemu-system-ppc64: pSeries SLOF firmware requires >= 80ldMiB guest RMA (Real Mode Area memory)

Above '80ldMib' is in hex, and it means 0x80 MiB = 128 MiB.

Change format specifier for this value to use 'HWADDR_PRId', instead of
'HWADDR_PRIx' thus showing decimal value instead of hex.

Thus, change the message to below error:

    qemu-system-ppc64: pSeries SLOF firmware requires >= 128MiB guest RMA (Real Mode Area memory)

This is an RFC, as it confused me why does QEMU print that error even with '-m' >80 MB.

This patch can also be considered a personal preference to see it as a decimal value instead of hex.

Or maybe we can have '0x80 MiB' instead ?

Does the 'ldMiB' actually mean that the value is in hexadecimal ? I did not find a reason in git history.
