[PATCH v2 00/34] Sama7g5 Evaluation Kit support

[PATCH v2 00/34] Sama7g5 Evaluation Kit support

[Eugen Hristev]

Hello,

This series adds support for sama7g5 SoC DT and the sama7g5ek board.
I kept the original incremental development for this board, with each
commit's author and designated change, for traceability and for easier
reviewing.

The series starts from a basic devicetree and ends with a fully functional
board including SD-Card/MMC, i2c eeproms, ethernet.

Thanks,
Eugen

Changes in v2:
- fixed compatible for i2c eeprom, mac was not read correctly in latest u-boot version
- fixed some checkpatch warnings and some spacing

[PATCH v2 03/34] board: atmel: sama7g5ek: add SYS_MALLOC_F_LEN to SYS_INIT_SP_ADDR

[Eugen Hristev]

From: Claudiu Beznea <claudiu.beznea@microchip.com>

Heap base address is computed based on SYS_INIT_SP_ADDR by
subtracting the SYS_MALLOC_F_LEN value in
board_init_f_init_reserve().

[PATCH v2 34/34] ARM: dts: sama7g5ek: fix TXC pin configuration

[Eugen Hristev]

From: Nicolas Ferre <nicolas.ferre@microchip.com>

TXC line is directly connected from the SoC to the KSZ9131 PHY. There
is a transient state on this signal, before configuring it to RGMII,
which leads to packet transmit being blocked.
Keeping a pull-up when muxing this pin as function A (G0_TXCK) fixes
the issue.
