2018-04-06common: env_embedded: allow fine placement of environment objectChristophe Leroy
Commit 7653942b10e9e ("common/env_embedded.c: drop support for CONFIG_SYS_USE_PPCENV") dropped the .ppcenv section which was used in linking scripts to allow fine placement of embedded environment sections. This implies that GCC randomly places objects from env/embedded.o and environment is not guaranteed to be located at the correct address: 04003df8 g F .text 00000038 mii_init 04004000 g O .text 00000004 env_size 04004004 g O .text 00002000 environment 04006004 g F .text 00000040 .hidden __lshrdi3 This patch restores this capability by allocating each object marked with __UBOOT_ENV_SECTION__ into a different section. Hence 'environment' will be alone in .text.environment, allowing a fine placement in u-boot.lds with: . = DEFINED(env_offset) ? env_offset : .; env/embedded.o (.text.environment) Fixes: 7653942b10e9e ("common/env_embedded.c: drop support for CONFIG_SYS_USE_PPCENV") Cc: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>

2018-04-06powerpc: mpc8xx: initialisation of initial RAMChristophe Leroy
u-boot requires some RAM at startup, to store global data structure. RAM is also needed when we migrate to DM for some initial malloc This patch implements the proper init of that RAM by calling board_init_f_alloc_reserve() and board_init_f_init_reserve() Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>

Some malloc memory is needed at startup for DM model. Lets reorganise the use of the CPM dpram. The MPC866/885 dpram, we have 8kbytes dual port RAM, which is usable as: IMMR + 0x2000..0x2800: BD/Data/Microcode IMMR + 0x2800..0x2e00: BD/Data IMMR + 0x2e00..0x3800: BD/Data/Microcode IMMR + 0x3800..0x3a00: BD/Data IMMR + 0x3a00..0x3c00: BD/Data/Microcode IMMR + 0x3c00..0x4000: Parameters for the Peripheral Controllers Lets reallocate all BDs in the 3800..3a00 area and give the full 2800..2e00 for dynamic RAM allocation including global data That way, the microcode areas remain available if needed one day.

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.

2018-04-04net: sun8i-emac: add support for new EMAC DT bindingAndre Przywara
The Ethernet MAC used in newer Allwinner SoCs (H3, A64, H5) got an upstream Linux driver in v4.15. 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.
