From 65efaac425e948dc56db5cf315d0497faeddb5b0 Mon Sep 17 00:00:00 2001 From: Sean Anderson Date: Sat, 14 Oct 2023 16:48:04 -0400 Subject: [PATCH] test: spl: Add a test for the NOR load method Add a test for the NOR load method. Since NOR is memory-mapped we can substitute a buffer instead. The only major complication is testing LZMA decompression. It's too complex to implement LZMA compression in a test, and we have no in-tree compressor, so we just include some pre-compressed data. This data was generated through something like generate_data(plain, plain_size, "lzma") cat plain.dat | lzma | hexdump -C and was cleaned up further in my editor.
