tools/firmware/ihex2fw: Replace explicit alignment with ALIGN

2019-01-22T09:23:18Z

(X + 3) & ~3 is the same as ALIGN(X, 4), so replace all of the instances of the formwer in the code with the latter. While at it, introduce a helper variable 'record_size' to avoid duplicating length calculatin code. No functional change intended.

tools/firmware/ihex2fw: Simplify next record offset calculation

2019-01-22T09:23:17Z

We can convert original expression for 'writelen" to use ALIGN as follows: (p->len + 9) & ~3 => (p->len + 6 + 3) & ~3 => ALIGN(p->len + 6, 4) Now, subsituting "p->len + 6" with "p->len + sizeof(p->addr) + sizeof(p->len)" we end up with the same expression as used by kernel couterpart in linux/ihex.h: ALIGN(p->len + sizeof(p->addr) + sizeof(p->len), 4) That is a full size of the record, aligned to 4 bytes. No functional change intended.

tools: Add 'firmware' category and add ihex2fw tool

2018-11-11T20:58:27Z

Commit 5620a0d1aacd ("firmware: delete in-kernel firmware") removed ihex2fw tool together with the rest of the contents of firmware/ folder. Since that tool is quite useful for doing .ihex -> .fw converstion, restore its original source code to tools/firmware Suggested-by: Greg Kroah-Hartman Cc: Kyle McMartin Cc: Andrew Morton Cc: Masahiro Yamada Cc: David Woodhouse Cc: Greg Kroah-Hartman Cc: linux-kernel Signed-off-by: Andrey Smirnov Signed-off-by: Greg Kroah-Hartman
