Eugeniu Rosca [Mon, 1 Apr 2019 10:45:34 +0000 (12:45 +0200)]
fdt: boot_get_fdt: really boot w/o FDT when "goto no_fdt"

The 'no_fdt' goto label was introduced by v2015.01 commit [0] and it
had two review stages [1-2]. The *documented* purpose behind commit [0]
is (excerpt from commit description):

> allows both FDT and non-FDT kernels to boot by making the
> third parameter to the bootm/bootz optional

While [1] and [2] share the same goal, they have very different
implementations:
 - [1] was based on a very simple 'argc' check at function error out
   with returning success to the caller if the third parameter was NOT
   passed to bootm/bootz command. This approach had the downside of
   returning success to the caller even in case of legitimate internal
   errors, which should halt booting.
 - [2] added the "no_fdt" label and several "goto no_fdt" statements.
   This allowed to report the legitimate internal errors to the caller.

IOW the major difference between [1] and [2] is:
 - [1] boot w/o FDT if FDT address is not passed to boot{m,z,*}
 - [2] give *freedom* to the developer to boot w/o FDT from any
   (more or less) arbitrary point in the function flow (and here
   comes the peculiar aspect, which looks to be a leftover from [1])
   with the precondition that the 3rd argument (FDT address) is NOT
   provided to boot{m,z,*}. In practice, this means that only a subset
   of "goto no_fdt" end up booting w/o FDT while the other subset is
   returning an error to the caller.

This patch removes the peculiar behavior described above, such that
"goto no_fdt" performs really what it tells to the developer.

The motivation of this patch is to decrease the unneeded complexity
and increase the readability of boot_get_fdt().

fdt: boot_get_fdt: remove redundant zeroing out

Paranoid programming [1] lies at the foundation of proper software
development, but the repetitive zeroing-out of output arguments in the
context of the same function rather clutters the code and inhibits
further refactoring/optimization than is doing any good.

In boot_get_fdt(), we already perform zero/NULL-initialization of
*of_flat_tree and *of_size at the beginning of the function, so doing
the same at function error-out is redundant/superfluous.

Moreover, keeping the code unchanged might encourage the developers to
update *of_flat_tree and *of_size during some interim computations,
which is against the current design of boot_get_fdt(). Currently,
writing useful data into these arguments happens just before
successfully returning from boot_get_fdt() and it should better stay so.
