2017-08-31MLK-13140 ARM: imx: update REFTOP_VBGADJ according to fuse settingBai Ping
On i.MX6ULL, according to the latest REFTOP_TRIM fuse define, we need to set the REFTOP_VBGADJ bits in PMU_MISC0 register as below table: '000" - set REFTOP_VBGADJ[2:0] to 3'b000 '001" - set REFTOP_VBGADJ[2:0] to 3'b001 '010" - set REFTOP_VBGADJ[2:0] to 3'b010 '011" - set REFTOP_VBGADJ[2:0] to 3'b011 '100" - set REFTOP_VBGADJ[2:0] to 3'b100 '101" - set REFTOP_VBGADJ[2:0] to 3'b101 '110" - set REFTOP_VBGADJ[2:0] to 3'b110 '111" - set REFTOP_VBGADJ[2:0] to 3'b111 Signed-off-by: Bai Ping <ping.bai@nxp.com> (cherry picked from commit b2690f5cf54390999acb2f1f7b788bfd18fa11be) (cherry picked from commit 30ce7adebd443ef777e820c4a891cbb3b28ac671)

Per to design team, we need to set REFTOP_VBGADJ in PMU MISC0 according to the REFTOP_TRIM[2:0] fuse. the actually table is as below: '000' - set REFTOP_VBGADJ[2:0] to 3b'110 '110' - set REFTOP_VBGADJ[2:0] to 3b'000 '001' - set REFTOP_VBGADJ[2:0] to 3b'001 '010' - set REFTOP_VBGADJ[2:0] to 3b'010 '011' - set REFTOP_VBGADJ[2:0] to 3b'011 '100' - set REFTOP_VBGADJ[2:0] to 3b'100 '101' - set REFTOP_VBGADJ[2:0] to 3b'101 '111' - set REFTOP_VBGADJ[2:0] to 3b'111 Signed-off-by: Bai Ping <ping.bai@nxp.com> (cherry picked from commit 911fcf93bad8c0a595c350b92f107b626029559b) Conflicts: arch/arm/cpu/armv7/mx6/soc.c Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
2017-03-30imx: imx-common: add elf firmware supportStefan Agner
Support elf firmware files for the auxiliary Cortex-M4 core. This has the advantage that the user does not need to know to which address the binary has been linked to. However, in order to load the elf sections to the right address, we need to translate the Cortex-M4 core memory addresses to primary/host CPU memory addresses (U-Boot is typically running on the A7/A9 core). This allows to boot firmwares from any location with just using bootaux, e.g.: tftp ${loadaddr} low_power_demo.elf && bootaux ${loadaddr} Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
2017-03-30imx: imx-common: move aux core image parsing to common codeStefan Agner
For i.MX 6SoloX/i.MX 7 simple binary files are used to boot the auxiliary CPU core (Cortex-M4). This patch moves the "parsing" of this binary firmwares to the SoC independent code. This allows to add different binary formats more easily. While at it, also move the comment about the inner workings how to boot the Cortex-M4 core to a more appropriate location.

2016-10-04imx: mx6: fix USB bmode to use reserved valueStefan Agner
Currently the bmode "usb" uses BOOT_CFG1 to 0x01, -which means BOOT_CFG1[7:4] is set to b0000. According to Table 8-7 Boot Device Selection this is NOR/OneNAND and not Reserved. Use 0x10 which leads to b0001, which is a Reserved boot device. With that the SoC reliably falls back to the serial loader.

2015-05-15mx6: Set shared override bit in PL310 AUX_CTRL registerFabio Estevam
Having bit 22 cleared in the PL310 Auxiliary Control register (shared attribute override enable) has the side effect of transforming Normal Shared Non-cacheable reads into Cacheable no-allocate reads. Coherent DMA buffers in Linux always have a Cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption. This was inspired by a patch from Catalin Marinas [1] and also from recent discussions in the linux-arm-kernel list [2] where Russell King and Rob Herring suggested that bootloaders should initialize the cache.

2014-11-12arm: imx: make bmode command work with SPL/U-Boot comboNikita Kiryanov
The bmode command forces the SoC to use a specific boot device by writing its boot mode into SRC_GPR9, and notifying the SoC of the change using SRC_GPR10[28] bit: if the bit is on, bootROM uses the value in SRC_GPR9 instead of SRC_SMBR1 to determine the boot device. SPL on the other hand is oblivious to this distinction, so once the bootROM loads SPL from the device configured in SRC_GPR10, SPL will attempt to load U-Boot from the device configured in SRC_SMBR1, which is not updated by the bootROM to the value in SRC_GPR9. The result is that the selected boot device is not used across all the boot stages. Update spl_boot_device() to look at gpr9 when necessary.
