| * | arm: mxs: Add 'Wait for JTAG user' if booted in JTAG modeGraeme Russ2015-02-102-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Russ2015-02-101-2/+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 Russ2015-02-104-5/+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>

It currently includes those two boards: platinum-titanium ----------------- This is the same board as the titanium that is already supported in mainline U-Boot. But its now moved to this new platform to support multiple "flavors" of imx6 boards in one directory. Its also moved to support SPL booting. And with this we use the run-time DDR configuration of this SPL support. The board is equipped with the Micron MT41J128M16JT-125 DDR chips. We now can remove the DDR related registers tuples from the imximage.cfg file. As all this is done in the SPL at run-time. platinum-picon -------------- This board is new and based on the MX6DL with 1GiB DDR using the Micron MT41K256M16HA DDR3 chips. Its also equipped with 2 NAND chips (each 512MiB). Signed-off-by: Stefan Roese <sr@denx.de> Cc: Stefano Babic <sbabic@denx.de> Cc: Pieter Ronsijn <pieter.ronsijn@barco.com>

Also it allows us to build U-Boot for any ARC core with the same one toolchain because we don't rely on pre-built libgcc. For example: * we may use little-endian toolchain but build U-Boot for ether endianess * we may use non-multilibbed uClibc toolchain but build U-Boot for whatever ARC CPU flavour that current GCC supports Private libgcc built from generic C implementation contributes only 144 bytes to .text section so we don't see significant degradation of size: --->8--- $ arc-linux-size u-boot.libgcc-prebuilt text data bss dec hex filename 222217 24912 214820 461949 70c7d u-boot.libgcc-prebuilt $ arc-linux-size u-boot.libgcc-private text data bss dec hex filename 222361 24912 214820 462093 70d0d u-boot.libgcc-private --->8--- Also I don't notice visible performance degradation compared to pre-built libgcc (where at least "*div*" functions are had-written in assembly) on typical operations of downloading 10Mb uImage over TFTP and bootm.
