| * SPI: mxc_spi: delay initialisation until claim busMarkus Niebel2014-10-27-16/+21
| | | | | | | | | | | | | | | | | | it is not correct to init for a specific slave in spi_setup_slave. instead buffer the values and delay init until spi_claim_bus.

| | | | | | | | | | | | | | | | | | | | | | | | the second reset prevents other registers to be written. This will prevent to have the correct signal levels for SCLK before writing to the config reg in spi_xchg_single.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The variable d is used in rather questionable way. Rework the code a bit so it's clearer what it does. Also, rename the variable from d to data to make it's name less mysterious. Finally, change it's data type to uint32_t , since it's accessed as a 32bit number.

* | | | 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.
