* Update buildroot-patches for 2020.11-rc1 buildroot * Update buildroot to 2020.11-rc1 Signed-off-by: Stefan Agner <stefan@agner.ch> * Don't rely on sfdisk --list-free output The --list-free (-F) argument does not allow machine readable mode. And it seems that the output format changes over time (different spacing, using size postfixes instead of raw blocks). Use sfdisk json output and calculate free partition space ourselfs. This works for 2.35 and 2.36 and is more robust since we rely on output which is meant for scripts to parse. * Migrate defconfigs for Buildroot 2020.11-rc1 In particular, rename BR2_TARGET_UBOOT_BOOT_SCRIPT(_SOURCE) to BR2_PACKAGE_HOST_UBOOT_TOOLS_BOOT_SCRIPT(_SOURCE). * Rebase/remove systemd patches for systemd 246 * Drop apparmor/libapparmor from buildroot-external * hassos-persists: use /run as directory for lockfiles The U-Boot tools use /var/lock by default which is not created any more by systemd by default (it is under tmpfiles legacy.conf, which we no longer install). * Disable systemd-update-done.service The service is not suited for pure read-only systems. In particular the service needs to be able to write a file in /etc and /var. Remove the service. Note: This is a static service and cannot be removed using systemd-preset. * Disable apparmor.service for now The service loads all default profiles. Some might actually cause problems. E.g. the profile for ping seems not to match our setup for /etc/resolv.conf: [85503.634653] audit: type=1400 audit(1605286002.684:236): apparmor="DENIED" operation="open" profile="ping" name="/run/resolv.conf" pid=27585 comm="ping" requested_mask="r" denied_mask="r" fsuid=0 ouid=0

# Number signs (#) appearing inside a macro reference or function invocation
|
|
# no longer introduce comments and should not be escaped with backslashes:
|
|
# thus a call such as:
|
|
# foo := $(shell echo '#')
|
|
# is legal. Previously the number sign needed to be escaped, for example:
|
|
# foo := $(shell echo '\#')
|
|
# Now this latter will resolve to "\#". If you want to write makefiles
|
|
# portable to both versions, assign the number sign to a variable:
|
|
# H := \#

# foo := $(shell echo '$H')

# Case conversion macros. This is inspired by the 'up' macro from gmsl
|
|
# (http://gmsl.sf.net). It is optimised very heavily because these macros
|
|
# are used a lot. It is about 5 times faster than forking a shell and tr.
|
|
#
|
|
# The caseconvert-helper creates a definition of the case conversion macro.
|
|
# After expansion by the outer $(eval ), the UPPERCASE macro is defined as:
|
|
# $(strip $(eval __tmp := $(1)) $(eval __tmp := $(subst a,A,$(__tmp))) ... )
|
|
# In other words, every letter is substituted one by one.
|
|
#
|
|
# The caseconvert-helper allows us to create this definition out of the
|
|
# [FROM] and [TO] lists, so we don't need to write down every substition
|
|
# manually. The uses of $ and $$ quoting are chosen in order to do as
|
|
# much expansion as possible up-front.
|
|
#
|
|
# Note that it would be possible to conceive a slightly more optimal
|
|
# implementation that avoids the use of __tmp, but that would be even
|
|
# more unreadable and is not worth the effort.

# This macro properly escapes a command string, then prints it with printf:
|

|
|
# - first, backslash '\' are self-escaped, so that they do not escape
|
|
# the following char and so that printf properly outputs a backslash;
|
|
#
|
|
# - next, single quotes are escaped by closing an existing one, adding
|
|
# an escaped one, and re-openning a new one (see below for the reason);
|
|
#
|
|
# - then '%' signs are self-escaped so that the printf does not interpret
|
|
# them as a format specifier, in case the variable contains an actual
|
|
# printf with a format;
|
|
#
|
|
# - finally, $(sep) is replaced with the literal '\n' so that make does
|
|
# not break on the so-expanded variable, but so that the printf does
|
|
# correctly output an LF.

# Note: this must be escaped in this order to avoid over-escaping the
|
|
# previously escaped elements.
