omap: Don't use hw_error() in device init() methods
...
Device init() methods aren't supposed to call hw_error(), they should
report the error and fail cleanly. Do that.
The errors are all device misconfiguration. All callers use
qdev_init_nofail(), so this patch merely converts hw_error() crashes
into &error_abort crashes. Improvement, because now it crashes closer
to where the misconfiguration bug would be, and a few more bad
examples of hw_error() use are gone.

arm: Use g_new() & friends where that makes obvious sense
...
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).

Convert ffs() != 0 callers to ctz32()
...
There are a number of ffs(3) callers that do roughly:
bit = ffs(val);
if (bit) {
do_something(bit - 1);
}
This pattern can be converted to ctz32() like this:
zeroes = ctz32(val);
if (zeroes != 32) {
do_something(zeroes);
}

hw: cannot_instantiate_with_device_add_yet due to pointer props
...
Pointer properties can be set only by code, not by device_add. A
device with a pointer property can work with device_add only when the
property may remain null.
This is the case for property "interrupt_vector" of device
"etraxfs,pic". Add a comment there.
Set cannot_instantiate_with_device_add_yet for the other devices with
pointer properties, with a comment explaining why.
Juha Riihimäki and Peter Maydell deserve my thanks for making "pointer
property must not remain null" blatantly obvious in the OMAP devices.
Only device "smbus-eeprom" is actually changed. The others are all
sysbus devices, which get cannot_instantiate_with_device_add_yet set
in their abstract base's class init function. Setting it again in
their class init function is technically redundant, but serves as
insurance for when sysbus devices become available with device_add,
and as documentation.
