* powerpc: mpc8xx: remove get_immr() argumentChristophe Leroy2018-04-063-6/+4
| | | | | | get_immr() is always called with 0 as an argument, so it is useless. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
* powerpc: mpc8xx: make get_immr() independent of CONFIG_8xxChristophe Leroy2018-04-061-2/+1
| | | | | | | | | | SPRN_IMMR is defined regardless of the CPU. Therefore, there is no point in enclosing get_immr() inside a #ifdef CONFIG_8xx As it a static inline function, it will in any case only be compiled in functons using it. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
* powerpc: mpc8xx: get rid of the multiple PVR_ valuesChristophe Leroy2018-04-062-5/+3

* powerpc: mpc8xx: harmonise initialisation of the immap local pointerChristophe Leroy2018-04-062-5/+3
| | | | | | | | | | | | | | In most places, immap local pointer is defined as immap_t __iomem *immap = (immap_t __iomem *)CONFIG_SYS_IMMR; In a few places, it is defined as immap_t __iomem *immap = (immap_t __iomem *)(immr & 0xFFFF0000); This patch replaces the few of the latest form by the other one. The two are fully equivalent since SPRN_IMMR is set with CONFIG_SYS_IMMR very early in start.S Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>

This one uses a slightly different binding from the original one used by the U-Boot driver. The differences to the old binding are: - The "syscon" address is held in a separate node, referenced via a phandle in the "syscon" property. - The reference to the PHY is held in a property called "phy-handle", not "phy". - The PHY register is at offset 0x30 in the syscon device, not at 0. - The internal PHY is activated when the node, which phy-handle points to, is a child node of an "allwinner,sun8i-h3-mdio-internal" node. Teach the U-Boot driver how to find its resources in a "new-style" DT, so that we can use a Linux kernel compatible DT for U-Boot as well. This keeps support for the old binding for now, to allow a smooth transition.

However, those old SoCs had a DMA engine that has been replaced since the A31 by another DMA controller that is no longer compatible. Since the code directly uses that DMA controller, it cannot operate properly on the later SoCs, while the NAND controller has not changed. There's two paths forward, the first one would have been to add support for that DMA controller too, the second to just remove the DMA usage entirely and rely on PIO. The later has been chosen because CPU overload at this stage is not an issue and it makes the driver more generic, and easier to understand.
