By that I mean this path series support fastboot function on rk3288, so 
far, host only has the ability push image to device.
We need further configuration for partition so that the image could 
flash to the mmc device.
Each of 3288 boards(firefly-rk3288, rock2) has a different partition 
setting, that's why I add the GPT partition on rk3288_common.h,
and didn't add the partition setting to ENV. If someone would like to 
use fastboot function on rk3288 board(ie. firefly-rk3288), he shall
configure partition in firefly-rk3288.h. like:
#define PARTS_DEFAULT \
     "uuid_disk=${uuid_gpt_disk};" \
     "name=loader,start=32K,size=4000K,uuid=${uuid_gpt_loader};" \
     "name=reserved,size=64K,uuid=${uuid_gpt_reserved};" \
     "name=misc,size=4M,uuid=${uuid_gpt_misc};" \
     "name=recovery,size=32M,uuid=${uuid_gpt_recovery};" \
     "name=boot_a,size=32M,uuid=${uuid_gpt_boot_a};" \
     "name=boot_b,size=32M,uuid=${uuid_gpt_boot_b};" \
     "name=system_a,size=818M,uuid=${uuid_gpt_system_a};" \
     "name=system_b,size=818M,uuid=${uuid_gpt_system_b};" \
     "name=vendor_a,size=50M,uuid=${uuid_gpt_vendor_a};" \
     "name=vendor_b,size=50M,uuid=${uuid_gpt_vendor_b};" \
     "name=cache,size=100M,uuid=${uuid_gpt_cache};" \
     "name=metadata,size=16M,uuid=${uuid_gpt_metadata};" \
     "name=persist,size=4M,uuid=${uuid_gpt_persist};" \
     "name=userdata,size=-,uuid=${uuid_gpt_userdata};\0" \

#undef CONFIG_EXTRA_ENV_SETTINGS
#define CONFIG_EXTRA_ENV_SETTINGS \
     "partitions=" PARTS_DEFAULT \

In short, I don't think "cannot find partition" is an issue. Does it 
make sense to you?
