[RFC PATCH linux dev-5.4 2/4] ARM: configs: aspeed-g5: Enable modules

[Andrew Jeffery]

This is a step on the path to enabling kprobes, which depend on
CONFIG_MODULES=y.

Setting CONFIG_MODULES=y results in the following change in kernel size:

Before:
         $ size vmlinux
            text    data     bss     dec     hex filename
         8140500 2440582  178904 10759986         a42f32 vmlinux
         $ stat --printf '%s\n' arch/arm/boot/zImage
         3445200

After:
         $ size vmlinux
            text    data     bss     dec     hex filename
         8240349 2388862  172304 10801515         a4d16b vmlinux
         $ stat --printf '%s\n' arch/arm/boot/zImage
         3458368

This gives a 41,529 byte increase to vmlinux and a 13,168 byte increase
to the size of the compressed kernel image. In the most constrained BMC
flash layout (arch/arm/boot/dts/openbmc-flash-layout.dtsi) this change
decreases the free space in the kernel partition from 1,011,248 bytes to
998,080 bytes.

CONFIG_HW_RANDOM=y seems to come along for the ride with the
`./scripts/config -e modules && make olddefconfig && make
savedefconfig`. The measurements above include it, I haven't
investigated why it gets enabled or what effect disabling it might have
on the numbers.
