2019-01-22tools/firmware/ihex2fw: Replace explicit alignment with ALIGNAndrey Smirnov1-2/+4
(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.

2019-01-22tools/firmware/ihex2fw: Simplify next record offset calculationAndrey Smirnov1-1/+10
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.

2018-11-11tools: Add 'firmware' category and add ihex2fw toolAndrey Smirnov2-0/+294
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 <gregkh@linuxfoundation.org> Cc: Kyle McMartin <kyle@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Masahiro Yamada <yamada.masahiro@socionext.com> Cc: David Woodhouse <dwmw2@infradead.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: linux-kernel <linux-kernel@vger.kernel.org> Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
