* ARM: mmu: fix cache flushing when replacing a section with a PTELucas Stach2018-07-271-45/+32
| | | | | | | | | | | | | | When replacing a section with a PTE, we must make sure that the newly initialized PTE entries are flushed from the cache before changing the entry in the TTB. Otherwise a L1 TLB miss causes the hardware pagetable walker to walk into a PTE with undefined content, causing exactly that behaviour. Move all the necessary cache flushing to arm_create_pte(), to avoid any caller getting this wrong in the future.

* i.MX: iomuxv3: restore NO_PAD_CTRL semanticAlexander Kurz2018-07-131-3/+5
| | | | | | | | | | | | | A NO_PAD_CTRL flag used to keep a pad configuration untouched. With commit 094820a63bfd ("i.MX: iomuxv3: Use helper functions in iomux-v3.h") the NO_PAD_CTRL semantic changed to set a pad configurations to zero, which breaks non-DT boards, where NO_PAD_CTRL is freqently used to keep a boot-up default pad configuration, which often is non zero. Restore the old semantic, dont write PAD_CTRL when NO_PAD_CTRL is set. Signed-off-by: Alexander Kurz <akurz@blala.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | OpenSSL 1.1.x made some of the types opaque, so peeking inside directly doesn't work anymore. Use the correct accessors instead. I've dropped the algorithm check, as EVP_PKEY_get0_RSA() already verifies that the pubkey is RSA and returns NULL if it isn't.

| * VFxxx: DCD: Remove read leveling and gate training delaysAndrey Smirnov2018-06-133-45/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Read leveling delays are being specified as zero, so they are as good as disabled and can be safely dropped. Gate training delay is specified as 4/128 tCK for both data slices. This setting, when applied to Data Byte 1, makes that slice unusable* during POR startup which is somehow is mitigated by double-reset hack in DCD. Dropping gate training delays allows both VF610 Tower board and ZII VF610 Dev board to sucessfully PoR-boot without the need for double resetting of the DDRMC. * The board fails to boot. When examined via JTAG in such a state only even bytes of DDR memory are functional. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although upstream U-Boot does not initialize this register in vf610-twr code (it does so in code for Phytec's PCM052) multiple revisions of VFxxx Controller Reference Manual state: 5.2.6.1 DUMMY PADS (DDR/QuadSPI) There are two dummy pads that are useful for timing calibration of DDR. These pads are internal only, but there corresponding IOMUX register need to be programmed for correct operation of DDR. These registers are: * IOMUXC_DUMMY_DDRBYTE1 (0x400482DC) * IOMUXC_DUMMY_DDRBYTE2 (0x400482E0) DDR: Dummy pads for DDR must be configured before any DDR I/O transactions are done. These pads simulate the input delay of the I/O buffers from the DRAM devices and DDR configures the delays accordingly. Although current DCD works as is, add writes for those registers for the sake of completness.
