2015-08-12ARM: SPL: Use CONFIG_SPL_DM not CONFIG_DMTom Rini
We now have the CONFIG_SPL_DM for code within SPL to toggle caring about DM or not. Without this change platforms that do enable CONFIG_DM but not CONFIG_SPL_DM may be broken (such as OMAP5). Cc: Albert Aribaud <albert.u.boot@aribaud.net> Signed-off-by: Tom Rini <trini@konsulko.com>
2015-03-04arm: Reduce the scope of lowlevel_init()Simon Glass
This function has grown into something of a monster. Some boards are setting up a console and DRAM here in SPL. This requires global_data which should be set up in one place (crt0.S). There is no need for SPL to use s_init() for anything since board_init_f() is called immediately afterwards. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-01-14arm: use canonical sub mnemonicAndreas Bießmann
Building some arm boards with older binutils may produce errors like this: ---8<--- crt0.S: Assembler messages: crt0.S:70: Error: register expected, not '#(184)' -- `sub sp,#(184)' --->8--- Use canonical version of the subtract mnemonic to avoid those issues.

2013-09-23ARM: use r9 for gdJeroen Hofstee
To be more EABI compliant and as a preparation for building with clang, use the platform-specific r9 register for gd instead of r8. note: The FIQ is not updated since it is not used in u-boot, and under discussion for the time being. The following checkpatch warning is ignored: WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl> cc: Albert ARIBAUD <albert.u.boot@aribaud.net>

2013-05-10ARM: OMAP: Cleanup boot parameters usageSRICHARAN R
The boot parameters are read from individual variables assigned for each of them. This been corrected and now they are stored as a part of the global data 'gd' structure. So read them from 'gd' instead. Signed-off-by: Sricharan R <r.sricharan@ti.com> [trini: Add igep0033 hunk] Signed-off-by: Tom Rini <trini@ti.com>
2012-09-01armv7: Make lowlevel_init.S's lowlevel_init do ABI compatible stackTom Rini
Make sure that when we setup the stack before calling s_init() we have the stack have 8-byte alignment for ABI compliance. Tested-by: Allen Martin <amartin@nvidia.com> Signed-off-by: Tom Rini <trini@ti.com>
2012-09-01omap4/5/am33xx: Make lowlevel_init available to all armv7 platformsTom Rini
Make the lowlevel_init function that these platforms have which just sets up the stack and calls a C function available to all armv7 platforms. As part of this we change some of the macros that are used to be more clear. Previously (except for am335x evm) we had been setting CONFIG_SYS_INIT_SP_ADDR to a series of new defines that are equivalent to simply referencing NON_SECURE_SRAM_END. On am335x evm we should have been doing this initially and do now. Cc: Sricharan R <r.sricharan@ti.com> Tested-by: Allen Martin <amartin@nvidia.com> Signed-off-by: Tom Rini <trini@ti.com>
