From 40d5bf64408a0e103f8149f941ea50fbbb11dc91 Mon Sep 17 00:00:00 2001 From: Alexey Neyman Date: Fri, 23 Nov 2018 22:14:07 -0800 Subject: Add moxiebox as a choice for libc This required some rework of the libc selection, as moxiebox is a layer on top of another libc - newlib. Also, moxiebox'es host VM (`sandbox`) needs a libcrypto on the host. We will not have it if we're cross-compiling a canadian cross. Fortunately, all moxiebox needs from libcrypto is SHA256, and it already includes a standalone implementation of SHA256 in its runtime. Provide a little wrapper that allows moxiebox use that implementation for the host binary, too. Also, automate collecting/printing the list of all packages in a given category (e.g. LIBC or COMP_TOOLS), generate a list of all Kconfig symbols for a given category.
