* dm: sunxi: Add support for serial using driver modelSimon Glass2014-11-05-0/+4
| | | | | | | | | | Add a driver for the designware serial UART used on sunxi. This just redirects to the normal ns16550 driver. Add a stdout-path to the device tree so that the correct UART is chosen. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
* dm: sunxi: Add pinmux functions which take a bank parameterSimon Glass2014-11-05-12/+24
| | | | | | | | | | With driver model we will have access to a bank pointer, so we want to use it rather than converting back to a number, and then back to a bank pointer. Add functions to provide this feature. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>

Always keep all sections in u-boot ELF binary. Move all unneeded sections after _end to avoid allocating space in the final binary. Also remove .deadcode section which is now obsolete. removed section .deadcode because the original symptoms were not visible anymore. Unfortuneatly the binutils bug still exists. The size of .rel.dyn section is often bigger than needed for all entries. But objcopy only allocates space as much as required for all reloc entries. Thus there is a gap between the last entry and __rel_dyn_end in u-boot.bin. If u-boot is booted from RAM (e.g. in SPL scenarios) that area could contain garbage data which could lead to CPU exceptions during relocation.

* | | arm: make .vectors section allocatableGeorges Savoundararadj2014-10-29-1/+1

The consequence of that is the non-relocation of the section .vectors symbols : _undefined_instruction, _software_interrupt, _prefetch_abort, _data_abort, _not_used, _irq and _fiq. Before commit 41623c91, the exception vectors were in a .text section. The .text section has the attributes allocatable and executable [1]. In commit 41623c91, a specific section is created, called .vectors, with the attribute executable only. What have changed between commit 41623c91^ and 41623c91 is the attribute of the section which contains the exception vectors. An allocatable section is "a section [that] occupies memory during process execution" [1] which is the case of the section .vectors. Adding the lacking attribute (SHF_ALLOC or "a") for the definition of the section .vectors fixed the issue. To summarize, the fix has to mark .vectors as allocatable because the exception vectors reside in "memory during execution" and they need to be relocated.

Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected for CPU_ARM1176 and CPU_V7. For each target, the corresponding CPU is selected and the definition of SYS_CPU in the corresponding Kconfig file is removed. Also, it removes redundant "string" type in some Kconfig files.
