2016-07-04ast2400: add SPI flash slavesCédric Le Goater
Each controller on the ast2400 has a memory range on which it maps its flash module slaves. Each slave is assigned a memory segment for its mapping that can be changed at bootime with the Segment Address Register. This is not supported in the current implementation so we are using the defaults provided by the specs. Each SPI flash slave can then be accessed in two modes: Command and User. When in User mode, accesses to the memory segment of the slaves are translated in SPI transfers. When in Command mode, the HW generates the SPI commands automatically and the memory segment is accessed as if doing a MMIO. Other SPI controllers call that mode linear addressing mode. For this purpose, we are adding below each crontoller an array of structs gathering for each SPI flash module, a segment rank, a MemoryRegion to handle the memory accesses and the associated SPI slave device, which should be a m25p80. Only the User mode is supported for now but we are preparing ground for the Command mode. The framework is sufficient to support Linux.

2016-07-04ast2400: add SMC controllers (FMC and SPI)Cédric Le Goater
The Aspeed AST2400 soc includes a static memory controller for the BMC which supports NOR, NAND and SPI flash memory modules. This controller has two modes : the SMC for the legacy interface which supports only one module and the FMC for the new interface which supports up to five modules. The AST2400 also includes a SPI only controller used for the host firmware, commonly called BIOS on Intel. It can be used in three mode : a SPI master, SPI slave and SPI pass-through Below is the initial framework for the SMC controller (FMC mode only) and the SPI controller: the sysbus object, MMIO for registers configuration and controls. Each controller has a SPI bus and a configurable number of CS lines for SPI flash slaves. The differences between the controllers are small, so they are abstracted using indirections on the register numbers. Only SPI flash modules are supported.

2015-09-07arm: Use g_new() & friends where that makes obvious senseMarkus Armbruster
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t.

To get it out of the default GPIO list. This allows child devices to use the un-named GPIO namespace without having to be SSI aware. That is, there is no more need for machines to know about the obscure policy where GPIO 0 is the SSI chip-select and GPIO 1..N are the concrete class GPIOs (defined locally as 0..N-1). This is most notable in stellaris, which uses a device which has both SSI and concrete level GPIOs.
