Because, rather than pass in ATAGs or set the memory on the command line,
they instead wanted to hard-code it in C - something which still happens
today:

arch/arm/mach-msm/board-halibut.c
arch/arm/mach-msm/board-mahimahi.c
arch/arm/mach-msm/board-sapphire.c
arch/arm/mach-msm/board-trout.c
arch/arm/mach-pxa/eseries.c
arch/arm/mach-pxa/spitz.c
arch/arm/mach-s3c2412/mach-smdk2413.c
arch/arm/mach-s3c2412/mach-vstms.c
arch/arm/mach-tegra/board-harmony.c

This is part of the on-going pain of poor quality boot loaders.
