Comment could be a bit more specific about what the problem is and how
changing the hard-coded "32" fixes it.

Haven't tested the cross compilation part myself, but this causes no
errors for 32-bit or 64-bit builds on my system. So, with some more
detail on the specifics of the fix in the commit message:

I'm with Bruce.  I'd like to know exactly whats going on here.  I dont have an
ARM system handy, so could you please post the errors that you are seeing here?
Is ADDR_SIZE not defined on BE for ARM or some such?  That seems like it should
be fixed, rather than this change.

The original code hard codes the conversion for sh_size to 32, which is 
incorrect.

The sh_size can be "Elf32_Word    sh_size" for 32 bit and "Elf64_Xword 
sh_size" for 64 bit systems.

This causes the symtab_stop to have reduced size and thus find can fail.
	info->symtab_stop  = RTE_PTR_ADD(hdr, sechdrs[i].sh_offset + 
sechdrs[i].sh_size);

we fixed it by replacing the hardcoded 32 with ADDR_SIZE is better.

I don't have access to Intel BE compiler, so could not check behavior 
there. One of difference in my env is that I am doing cross compilation 
on intel-x86-64 machine.
I used the following BE compiler
https://releases.linaro.org/components/toolchain/binaries/6.4-2017.11/aarch64_be-linux-gnu/gcc-linaro-6.4.1-2017.11-x86_64_aarch64_be-linux-gnu.tar.xz

Oh, my bad, you're correct, I thought it was 32 bits for both ABI's

[dpdk-dev] [PATCH v2 1/5] pmdinfogen: fix cross compilation for ARM BE

[Hemant Agrawal]

Cross compiling DPDK for BE mode on ARM results into errors
"PMDINFO portal/dpaa2_hw_dpio.o.pmd.c No drivers registered"

The original code assumes the sh_size to be 32 bit, while it can
be Elf32_Word or Elf64_Xword based on 32bit or 64 bit systems.

This patches replaces the sh_size conversion routines to use ADDR_SIZE

I'm not I'd agree with this as a "better" fix. Were the issues with the
previous version of just removing the braces. All the ifdefs are rather
ugly.

[dpdk-dev] [PATCH v3 1/5] pmdinfogen: fix cross compilation for ARM BE

[Hemant Agrawal]

Cross compiling DPDK for BE mode on ARM results into errors
"PMDINFO portal/dpaa2_hw_dpio.o.pmd.c No drivers registered"

The original code assumes the sh_size to be 32 bit, while it can
be Elf32_Word or Elf64_Xword based on 32bit or 64 bit systems.

This patches replaces the sh_size conversion routines to use ADDR_SIZE
