* zynq: timer: Fix hangs if network activity attempted after about one hourMichal Simek2014-02-19-2/+2
| | | | | | | | | | | | Cortex-A9 MPCore TRM' from ARM (ARM DDI 0407G ID072711) describes in the section 4.1.1 how this value calculation should be done. This patch fixes the problem if network activity such as ping or tftp is attempted after u-boot has been idle for an hour, it hangs, and cannot control-C out of it.

* zynq: Fix elf header generationMichal Simek2014-02-13-0/+99
| | | | | | | | | | | | This patch is here because of: "arm: keep all sections in ELF file" (sha1: 47ed5dd031d7d2c587e6afd386e79ccec1a1b7f7) Our tools expect to have elf with only LOAD header. Without this fix also PHDR, INTERP and DYNAMIC headers are available in ELF. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

| | | | | | | | | | | | | | | | | | | | | | Added support to find the bootmodes by reading slcr bootmode register. this can be helpful to autoboot the configurations w.r.t a specified bootmode. Added this functionality on board_late_init as it's not needed for normal initializtion part. Signed-off-by: Jagannadha Sutradharudu Teki <jaganna@xilinx.com>

Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file. Note: 'git show' will also list two files just because they are new: include/configs/am335x_igep0033.h include/configs/omap3_igep00x0.h
| * zynq: Use arch_cpu_init() instead of lowlevel_init()Michal Simek2013-10-17-0/+6
| | | | | | | | | | | | | | | | | | | | | | Zynq lowlevel_init() was implemented in C but stack pointer is setup after function call in _main(). Move architecture setup to arch_cpu_init() which is call as the first function in board_init_f() which already have correct stack pointer.
