2018-10-03riscv: Explicitly pass -march and -mabi to the compilerBin Meng
At present the compiler flag against which architecture and abi variant the riscv image is built for is not explicitly indicated which means the default compiler configuration is used. But this does not work if we want to build a different target (eg: 32-bit riscv images using a toolchain configured for 64-bit riscv). Fix this by explicitly passing -march and -mabi to the compiler. Since generically we don't use floating point in U-Boot, specify the RV[32|64]IMA ISA and software floating ABI. This also fix some alignment coding style issues.

While we are here, this also changes the Linux kernel entry parameters' type to support both 32-bit and 64-bit. Note the hart id is hardcoded to zero for now, and we should change to fill in it with the value read from mhartid CSR of the hart which this routine is currently running on.

2018-10-02mtd: mtdpart: implement proper partition handlingMiquel Raynal
Instead of collecting partitions in a flat list, create a hierarchy within the mtd_info structure: use a partitions list to keep track of the partitions of an MTD device (which might be itself a partition of another MTD device), a pointer to the parent device (NULL when the MTD device is the root one, not a partition). By also saving directly in mtd_info the offset of the partition, we can get rid of the mtd_part structure.

2018-10-02mtd: uboot: search for an equivalent MTD name with the mtdidsMiquel Raynal
Using an MTD device (resp. partition) name in mtdparts is simple and straightforward. However, for a long time already, another name was given in mtdparts to indicate a device (resp. partition) so the "mtdids" environment variable was created to do the match. Let's create a function that, from an MTD device (resp. partition) name, search for the equivalent name in the "mtdparts" environment variable thanks to the "mtdids" string.

2018-10-02mtd: mtdpart: add a generic mtdparts-like parserMiquel Raynal
The current parser is very specific to U-Boot mtdparts implementation. It does not use MTD structures like mtd_info and mtd_partition. Copy and adapt the current parser in drivers/mtd/mtd-uclass.c (to not break the current use of mtdparts.c itself) and write some kind of a wrapper around the current implementation to allow other commands to benefit from this parsing in a user-friendly way. This new function will allocate an mtd_partition array for each successful call. This array must be freed after use by the caller. The given 'mtdparts' buffer pointer will be moved forward to the next MTD device (if any, it will point towards a '\0' character otherwise).

2018-10-02rockchip: rk3188: explicitly set vcc_sd0 pin to gpio on rk3188-radxarockHeiko Stuebner
It is good practice to make the setting of gpio-pinctrls explicitly in the devicetree, and in this case even necessary. Rockchip boards start with iomux settings set to gpio for most pins and while the linux pinctrl driver also implicitly sets the gpio function if a pin is requested as gpio that is not necessarily true for other drivers. The issue in question stems from uboot, where the sdmmc_pwr pin is set to function 1 (sdmmc-power) by the bootrom when reading the 1st-stage loader. The regulator controlled by the pin is active-low though, so when the dwmmc hw-block sets its enabled bit, it actually disables the regulator. By changing the pin back to gpio we fix that behaviour.

While I only tested in somewhat bigger steps, 32MHz for example hung the controller, while reducing it to 16MHz worked just fine and is reasonably fast to load a kernel from mmc.

While trying to enable the dw_mmc on rk3188 I managed to confuse and hang the dw_mmc controller into not delivering further data. The fifo state never became ready and the driver was iterating in the while loop reading 0-byte packets forever. So inspired by how other implementations handle this, check the fifo- state beforhand and add a timeout to catch any glaring fifo issues without hanging uboot altogether.
