[U-Boot] [PATCH] ARM: rmobile: Convert to bootm_size

[Eugeniu Rosca <roscaeugeniu@gmail.com>]

Hello Marek,

May I ask for your opinion on Renesas commits [1-2] especially in
light of the `bootm_size` changes done in your patch?
The topics look orthogonal to me, but I kindly ask for your confirmation.

Also, purely related to the `bootm_size` patch, compiling v2019.04-rc3
U-Boot for H3-Salvator-X with the diff [3] applied, I get:

common/image.c: In function 'env_get_bootm_mapsize':
common/image.c:520:2: error: #error "Take bootm_size from CONFIG"
 #error "Take bootm_size from CONFIG"
  ^~~~~

Does this mean the "CONFIG_SYS_BOOTMAPSZ" definition has to be removed
from include/configs/rcar-gen3-common.h, to allow the patch to have
the desired effect?

[3] Brutal way to reveal the active bootm_size:
diff --git a/common/image.c b/common/image.c
