| * edminiv2: switch to SPLAlbert ARIBAUD2015-02-25-0/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ED Mini V2 is based on Orion 5x which boots at fixed address 0xFFFF0000 in NOR Flash. Place SPL there, and switch U-Boot from .bin to .img format, stored in NOR Flash at 0xFFF90000. Note: this patch was tested on HW and works, i.e. it boots U-Boot properly, but SPL console output currently does not appear, due to GD being trashed by arch/arm/lib/spl.c. This trashing is soon to be removed, and then ED Mini V2 SPL console output will become visible. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

| | | | | | | | | | | | | | | | | | | | | | When booting in JTAG mode, there is no way to use soft break-points, and no way of knowing when SPL has finished executing (so the user can issue a 'halt' command to load u-boot.bin for example) Add a debug output and simple loop to stop execution at the completion of the SPL initialisation as a pseudo break-point when booting in JTAG mode Signed-off-by: Graeme Russ <gruss@tss-engineering.com>
| * arm: mxs: Enable booting of mx28 without batteryGraeme Russ2015-02-10-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Section 4.1.2 of Freescale Application Note AN4199 describes the configuration required to operate the mx28 from a 5V source without a battery. This patch changes the behaviour of the dropout control of the DC-DC converter (refer to section 11.12.9 of the mx28 Application Processor Reference Manual - Document Number: MCIMX28RM, Rev 2, 08/2013) to the following: - Always use 4P2 Linear Regulator if CONFIG_SYS_MXS_VDD5V_ONLY is defined - Switch between 4P2 Linear Regulator and Battery, using whichever has the highest voltage if CONFIG_SYS_MXS_VDD5V_ONLY isnot set (this is the same as the pre-patch behaviour) Signed-off-by: Graeme Russ <gruss@tss-engineering.com> Signed-off-by: Damien Gotfroi <dgotfroi@greenwatch.be>
| * arm: mxs: Add debug outputs and comments to mxs SPL source filesGraeme Russ2015-02-10-5/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | It is difficult to track down fail to boot issues in the mxs SPL. Implement the following to make it easier: - Add debug outputs to allow tracing of SPL progress in order to track where failure to boot occurs. DEUBUG and CONFIG_SPL_SERIAL_SUPPORT must be defined to enable debug output in SPL - Add TODO comments where it is not clear if the code is doing what it is meant to be doing, even tough the board boots properly (these comments refer to existing code, not to any code added by this patch) Signed-off-by: Graeme Russ <gruss@tss-engineering.com>

* mx25: Fix boot hang by avoiding vector relocationFabio Estevam2015-01-08-0/+27
| | | | | | | | | | | | | | | | | | | | | Since commit 3ff46cc42b9d73d0 ("arm: relocate the exception vectors") mx25pdk hangs like this: CPU: Freescale i.MX25 rev1.2 at 399 MHz Reset cause: WDOG Board: MX25PDK I2C: ready DRAM: 64 MiB (hangs) Add a specific relocate_vectors macro that skips the vector relocation, as the i.MX25 SoC does not provide RAM at the high vectors address (0xFFFF0000), and (0x00000000) maps to ROM.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 3ff46cc4 fixed exception vectors setting in the general ARM case, by either copying the exception and indirect vector tables to normal (0x00000000) or high (0xFFFF0000) vectors address, or setting VBAR to U-Boot's base if applicable. i.MX27 SoC is ARM926E-JS, thus has only normal and high options, but does not provide RAM at 0xFFFF0000 and has only ROM at 0x00000000; it is therefore not possible to move or change its exception vectors. Besides, i.MX27 ROM code does provide an indirect vectors table but at a non-standard address and with the reset and reserved vectors missing. Turn the current vector relocation code into a weak routine called after relocate_code from crt0, and add strong version for i.MX27.
