From 337bbb6297775e8e9d664e96e96004f00d1d8c02 Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Fri, 24 Nov 2017 13:26:03 +0100 Subject: spl: fit: add SPL_FIT_IMAGE_TINY config to reduce code-size A minor code-size increase from the changes for tracking the os-type of FIT images and from infrastructure for recording the loadables into the the loaded FDT, broke the builds for sun50i and some OMAP2+ devices. This change adds a new config option (enabled by default for MACH_SUN50I, MACH_SUN50I_H5 and ARCH_OMAP2PLUS) that does skips these processing steps (bringing code size down to below the limit again). The os-type is not evaluated, but assumed to be IH_OS_UBOOT (i.e. taking the code-paths intended for backward-compatibility). Note that enabling this config option precludes any useful downstream processing, such as utilising a special calling convention for ATF or OPTEE, based on the os-type of the loadables.
