2019-07-11tpm: wait for valid statusRoman Kapl
The TPM specification says that the EXPECT_DATA bit is not valid until the VALID bit is set. Wait for that bit to be set. Fixes problems with Ifineon SPI TPM. Signed-off-by: Roman Kapl <rka@sysgo.com>
2019-07-11arm: spear: Return to BootROM if failing to boot from the main deviceMiquel Raynal
Overload the weak function board_boot_order() so that besides choosing the main boot device, we can fallback on USB boot by returning in the BootROM, eg. if the NOR flash is empty while it was the primary boot medium.

2019-07-11arm: spear: Support returning to BootROMMiquel Raynal
Implement the weak board_return_to_bootrom() function so that when enabling the spl_bootrom.c driver, one can make use of usbboot on spear platforms. All necessary information to return to the BootROM are stored in the BootROM's stack. The SPL stack pointer is reset so we save the BootROM's stack pointer into the SPL .data section.

2019-07-11arm: spear: Reference the link register with LR instead of R14Miquel Raynal
The link register is stored in R14. ARM assembly code allows to use the 'lr' name to reference it instead of 'r14' which is not very meaningful. Do the substitution to ease the reading. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Reviewed-by: Stefan Roese <sr@denx.de>
2019-07-11arm: spear: Use PUSH/POP mnemonics when relevantMiquel Raynal
Quoting ARM "RealView Compilation Tools Assembler Guide v4.0": PUSH and POP are synonyms for STMDB and LDM (or LDMIA), with the base register sp (r13), and the adjusted address written back to the base register. PUSH and POP are the preferred mnemonic in these cases. Let's follow this recommandation to ease the reading and substitute LDMIA/STMDB operations with PUSH/POP mnemonics.

2019-07-11km/spi: remove deprecated SPI flash driver code for KM Kirkwood boardsPascal Linder
KM Kirkwood boards now implement the driver model for its SPI flash interface. Therefore, the old board specific claim and release functions can be deleted. The preprocessor definition CONFIG_SYS_KW_SPI_MPP is yet unused as well. All its appearances and dependencies are removed in the kirkwood_spi driver, header files and finally the configuration whitelist.

2019-07-11km/spi: overwrite kirkwood_spi weak functions for KM Kirkwood boardsPascal Linder
As the SPI NOR and NAND devices share the same hardware pins, the MPP configuration has to be changed when claiming/releasing the bus. The current configuration is saved when claiming and restored when releasing. Furthermore, a general-purpose output is used to switch the chip-select signal. This is now also implemented for the DM part of the kirkwood_spi driver.

The weak functions, known from the legacy code, are added to the DM part as well. For this purpose, the release operation first needs to be implemented. KM Kirkwood boards will overwrite those weak functions to change the MPP configuration when claiming/releasing the bus, because the hardware pins are shared between the SPI NOR and NAND devices.

2019-07-11km: modify Kconfig file organization for KM boardsPascal Linder
As preparation for the upcoming transferring of configurations from header files to Kconfig, a common Kconfig file for all KM boards was created. For the moment, it only sources the other three, more specific, Kconfig files. Therefore, the architecture Kconfig files now include the common Kconfig file. Also, the configuration selection for KM boards was moved from the architecture Kconfig files to the board specific Kconfig files.
