[PATCH 9/9] ARM: renesas: Add R8A779G0 V4H White Hawk board code

Tue Feb 28 22:37:08 CET 2023
From: Hai Pham <hai.pham.ud at renesas.com>
Add board code for R8A779G0 V4H White Hawk board.
Reviewed-by: Marek Vasut <marek.vasut+renesas at mailbox.org>
Signed-off-by: Hai Pham <hai.pham.ud at renesas.com>
Signed-off-by: Marek Vasut <marek.vasut+renesas at mailbox.org>
[Marek: Synchronize configuration symbols which are now switched to Kconfig
Mallocate gd->bd->bi_boot_params, i.e. drop the assignment
Sort headers, use clrbits_le32(), use BIT macros where appropriate
Use CONFIG_SYS_CLK_FREQ for counter frequency instead of custom macro]
